phy: qcom-qmp: Add support for DP in USB3+DP combo phy
Add support for the USB3 + DisplayPort (DP) "combo" phy to the qmp phy
driver. We already have support for the USB3 part of the combo phy, so
most additions are for the DP phy.
Split up the qcom_qmp_phy{enable,disable}() functions into the phy init,
power on, power off, and exit functions that the common phy framework
expects so that the DP phy can add even more phy ops like
phy_calibrate() and phy_configure(). This allows us to initialize the DP
PHY and configure the AUX channel before powering on the PHY at the link
rate that was negotiated during link training.
The general design is as follows:
1) DP controller calls phy_init() to initialize the PHY and configure
the dp_com register region.
2) DP controller calls phy_configure() to tune the link rate and
voltage swing and pre-emphasis settings.
3) DP controller calls phy_power_on() to enable the PLL and power on
the phy.
4) DP controller calls phy_configure() again to tune the voltage swing
and pre-emphasis settings determind during link training.
5) DP controller calls phy_calibrate() some number of times to change
the aux settings if the aux channel times out during link training.
6) DP controller calls phy_power_off() if the link rate is to be
changed and goes back to step 2 to try again at a different link rate.
5) DP controller calls phy_power_off() and then phy_exit() to power
down the PHY when it is done.
The DP PHY contains a PLL that is different from the one used for the
USB3 PHY. Instead of a pipe clk there is a link clk and a pixel clk
output from the DP PLL after going through various dividers. Introduce
clk ops for these two clks that just tell the child clks what the
frequency of the pixel and link are. When the phy link rate is
configured we call clk_set_rate() to update the child clks in the
display clk controller on what rate is in use. The clk frequencies
always differ based on the link rate (i.e. 1.6Gb/s 2.7Gb/s, 5.4Gb/s, or
8.1Gb/s corresponding to various transmission modes like HBR1, HBR2 or
HBR3) so we simply store the link rate and use that to calculate the clk
frequencies.
The PLL enable sequence is a little different from other QMP phy PLLs so
we power on the PLL in qcom_qmp_phy_configure_dp_phy() that gets called
from phy_power_on(). This should probably be split out better so that
each phy has a way to run the final PLL/PHY enable sequence.
This code is based on a submission of this phy and PLL in the drm
subsystem.

phy: qcom-qmp: Move 'serdes' and 'cfg' into 'struct qcom_phy'
The serdes I/O region is where the PLL for the phy is controlled.
Sometimes the PLL is shared between multiple phys, for example in the
PCIe case where there are three phys inside the same wrapper. Other
times the PLL is for a single phy, i.e. some USB3 phys. To complete the
trifecta we have the USB3+DP combo phy where the USB3 and DP phys each
have their own serdes region because they have their own PLL while they
both share a common I/O region pertaining to the USB type-c pinout and
cable orientation.
Let's move the serdes iomem pointer into 'struct qmp_phy' so that we can
correlate PLL control to the phy that uses it. This allows us to support
the USB3+DP combo phy in this driver. This isn't a problem for the
3-lane/phy PCIe phy because there is a common init function that is the
only place the serdes region is programmed.
Furthermore, move the configuration data that contains most of the
register programming sequences to the qmp phy struct. This data isn't
qmp wrapper specific. It is phy specific data used to tune various
settings for things like pre-emphasis, bias, etc.

regfield handling in current driver code is made complicated

There's a bit of confusion on the matching pairs of poll vs double poll,
depending on if the request is a pure poll (IORING_OP_POLL_ADD) or
poll driven retry.
Add io_poll_get_double() that returns the double poll waitqueue, if any,
and io_poll_get_single() that returns the original poll waitqueue. With
that, remove the argument to io_poll_remove_double().
Finally ensure that wait->private is cleared once the double poll handler
has run, so that remove knows it's already been seen.

virtio: pci: constify ioreadX() iomem argument (as in generic implementation)
The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.
