Split off all code specific to the MaxSX8 cards to a separate ddbridge-sx8

mci_type to allow for using different attach handling for different cards.
As different cards can implement things differently (ie. support differing

common mci_base struct), this introduces the mci_cfg struct which is
initially used to hold a few specifics to the -sx8 submodule. While at it,
the handling of the i/q mode is adjusted slightly. Besides this and
handling mci_base and sx8_base struct pointers where needed, all code

media: em28xx: explicitly disable TS packet filter
The em28xx driver never touched the EM2874 register bits that control

while the Hauppauge WinTV dualHD enables discarding NULL packets by
default.
However, some applications require NULL packets, e.g. to determine the
load in DOCSIS segments, so discarding NULL packets is undesired for
such applications.
This patch simply extends the bit mask when starting or stopping the
transport stream packet capture, so that the filter bits are cleared.
It has been verified that this makes the Hauppauge WinTV dualHD pass
an unfiltered DVB-C stream including NULL packets, which it didn't
before.

media: s5p-mfc: Fix buffer look up in s5p_mfc_handle_frame_{new, copy_time} functions
Look up of buffers in s5p_mfc_handle_frame_new, s5p_mfc_handle_frame_copy_time
functions is not working properly for DMA addresses above 2 GiB. As a result
flags and timestamp of returned buffers are not set correctly and it breaks
operation of GStreamer/OMX plugins which rely on the CAPTURE buffer queue
flags.
Due to improper return type of the get_dec_y_adr, get_dspl_y_adr callbacks
and sign bit extension these callbacks return incorrect address values,
e.g. 0xfffffffffefc0000 instead of 0x00000000fefc0000. Then the statement:
"if (vb2_dma_contig_plane_dma_addr(&dst_buf->b->vb2_buf, 0) == dec_y_addr)"
is always false, which breaks looking up capture queue buffers.
To ensure proper matching by address u32 type is used for the DMA
addresses. This should work on all related SoCs, since the MFC DMA
address width is not larger than 32-bit.
Changes done in this patch are minimal as there is a larger patch series
pending refactoring the whole driver.

1) Context A schedules, queues and runs job A.
2) While the m2m device is running, context B schedules
and queues job B. Job B cannot run, because it has to
wait for job A.
3) Job A completes, calls v4l2_m2m_job_finish, and tries
to queue a job for context A, but since the context is
empty it won't do anything.
In this scenario, queued job B will never run. Fix this by calling
v4l2_m2m_try_run from v4l2_m2m_try_schedule.

media: imx274: add cropping support via SELECTION API
Currently this driver does not support cropping. The supported modes
are the following, all capturing the entire area:
- 3840x2160, 1:1 binning (native sensor resolution)
- 1920x1080, 2:1 binning
- 1280x720, 3:1 binning
The VIDIOC_SUBDEV_S_FMT ioctl chooses among these 3 configurations the
one that matches the requested format.
Add cropping support via VIDIOC_SUBDEV_S_SELECTION: with target
V4L2_SEL_TGT_CROP to choose the captured area, with
V4L2_SEL_TGT_COMPOSE to choose the output resolution.
To maintain backward compatibility we also allow setting the compose
format via VIDIOC_SUBDEV_S_FMT. To obtain this, compose rect and
output format are computed in the common helper function
__imx274_change_compose(), which sets both to the same width/height
values.
Cropping also calls __imx274_change_compose() whenever cropping rect
size changes in order to reset the compose rect (and output format
size) for 1:1 binning.
Also rename enum imx274_mode to imx274_binning (and its values from
IMX274_MODE_BINNING_* to IMX274_BINNING_*). Without cropping, the two
naming are equivalent. With cropping, the resolution could be
different, e.g. using 2:1 binning mode to crop 1200x960 and output a
600x480 format. Using binning in the names avoids any
misunderstanding. For the same reason, replace the 'size' field in
struct imx274_frmfmt with 'bin_ratio'.

media: em28xx: Fix dual transport stream operation
Addresses the following, which introduced a regression itself:
Commit
509f89652f83 ("media: em28xx: fix a regression with HVR-950")
The regression fix breaks dual transport stream support. Currently,
when a tuner starts streaming it sets alt mode on the USB interface.
The problem is, in a dual tuner model, both tuners share the same
USB interface, so when the second tuner becomes active and sets alt
mode on the interface it kills streaming on the other port.
This patch addresses the regression by only setting alt mode
on the USB interface during em28xx_start_streaming, if the
device is not a dual tuner model. This allows all older and
single tuner devices to explicitly set alt mode during stream
startup. Testers report both isoc and bulk DualHD models work
correctly with the alt mode set only once, in em28xx_dvb_init.

media: venus: implementing multi-stream support
This is implementing multi-stream decoder support. The multi-stream
will be used to enable/disable the primary/secondary decoder
outputs. Depending on formats on both decoder outputs we could
implement downscale, dithering and supporting UBWC (universal
bandwidth compression) formats. The UBWC compressed raw format is
used to optimize interconnect bandwidth for bigger resolutions
like 4K and hence we will get some power-saving benefits as well.
Both decoder outputs are distinguished by buffer_type field in
the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type
for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary
decoder output.
Starting from Venus 4xx the DPB buffers format must be UBWC, so
the multi-stream becomes mandatory for this Venus version. That
means that we need to allocate internally in the driver a set of
DPB buffers (with UBWC NV12 format) and give them to the firmware.
The other decoder output (we called it OPB) format will be NV12
linear format and with the same resolution (or smaller in case
the user wants to downscale).
The DPB buffers are used for decoder reference frames and those
have to be in a specific format (UBWC). So one decoder output is
used to fill those reference buffers while the other output is
used to fill the userspace buffers with the user requested format.
