[media] rc: ir-rc6-decoder: Add encode capability
Add the capability to encode RC-6 and RC-6A scancodes as raw events.
The protocol is chosen based on the specified protocol mask, and
whether all the required bits are set in the scancode mask, and none of
the unused bits are set in the scancode data.
The Manchester modulation helper is used several times with various
timings so that RC-6 header preamble, the header, header trailing bit
and the data itself can be modulated correctly.

[media] rc: ir-rc5-decoder: Add encode capability
Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw
events. The protocol is chosen based on the specified protocol mask,
and whether all the required bits are set in the scancode mask, and
none of the unused bits are set in the scancode data. For example a
scancode filter with bit 16 set in both data and mask is unambiguously
RC-5X.
The Manchester modulation helper is used, and for RC-5X it is used twice
with two sets of timings, the first with a short trailer space for the
space in the middle, and the second with no leader so that it can
continue the space.
The encoding in RC-5-SZ first inserts a pulse and then simply utilizes
the generic Manchester encoder available in rc-core.

[media] rtl2832: add support for GoTView MasterHD 3 USB tuner
GoTView MasterHD 3 is a DVB-T2/C USB 2.0 tuner.
It's based on the following components:
- USB bridge: RTL2832P (contains also DVB-T demodulator)
- Demodulator: Si2168-A30
- Tuner: Si2148-A20
The demodulator and the tuner will need firmwares. The Si2148 uses Si2158
firmware. Antti has the firmwares available for download:
http://palosaari.fi/linux/v4l-dvb/firmware/
Do note that for DVB-T either of the demodulators can be used. DVB-C and
DVB-T2 are only supported by the Si2168 demodulator. The driver will
register 2 frontends for the same adapter. Frontend 0 will be the RTL2832
demodulator and frontend 1 will be the Si2168 demodulator. The same
tuner is used for both.
As a consequence of the above, it's recommended to use application that
does implement proper DVBv5 support.
For some reason, the old I2C write method sporadically fails. Thus the
need for an option to only use the new I2C write method supported by the
RTL2832.

[media] si2157: support selection of IF interface
The chips supported by the si2157 driver have two IF outputs (either
pins 12+13 or pins 9+11). Instead of hardcoding the output to be used
add an option to choose which output shall be used.
As this patch changes the default behaviour, the IF interface is
specified in each driver currently using si2157 driver. This is to
keep bisectability.

[media] mantis: fix error handling
Remove dead code, make goto label names more expressive and add a label
in order to call mantis_dvb_exit if mantis_uart_init fails.
Also make sure that mantis_pci_exit is called if we fail the
mantis_stream_control call and that we call mantis_i2c_exit if
mantis_get_mac fails.

[media] marvell-ccic: fix RGB444 format
The RGB444 format swapped the red and blue components, fix this.
Rather than making a new BGR444 format (as I proposed initially), Jon prefers
to just fix this and return the colors in the right order. I think that makes
sense in this case.
Since the RGB444 pixel format is deprecated due to the ambiguous specification
of the alpha component we use the XRGB444 pixel format instead (specified as having
no alpha channel).
