Assign drm_atomic_helper_crtc_set_property helper to MDP4 and MDP5
crtcs' set_property ops. This replaces the custom funcs that
returned an error even for standard crtc properties.

Add HDMI PHY bindings. Update the example to use HDMI PHY.
Added a missing power-domains property in the HDMI core bindings. Also,
simplified HDMI TX's DT node name in the example.

Add support for the HDMI PHY/PLL found in MSM8996/APQ8096.
Unlike the previous PHYs supported in the driver, this doesn't need
the powerup/powerdown ops. The PLL prepare/unprepare clock ops
enable/disable the phy itself.

Adds HDMI 8996 PHY offsets. The offsets are divided into 3 parts:
- Core HDMI PHY registers
- HDMI PLL registers (part of QSERDES block)
- HDMI TX lane registers (part of QSERDES block)

Remove the old PHY ops managed by hdmi_platform_config and use them as ops
provided by the HDMI PHY driver.
Remove the old HDMI 8960 PLL code that used the top level HDMI TX mmio
base.
NOTE: With this commit, HDMI functionality will break until the HDMI
PHY/PLL register offsets in hdmi.xml.h aren't updated to be used as
separate domains.

Make HDMI core get its PHY by parsing the "phys" phandle. The core will use
this PHY reference to enable/disable PHY. The driver defers probe until PHY
isn't available.
The DT bindings used here is the same as the one used for PHYs using the
common PHY framework bindings.

Add a helper to initialize PLL in the PHY driver. HDMI PLLs are going to
have their own mmio base different from that of PHY.
For the clock code in hdmi_phy_8960.c, some changes were needed for it to
work with the updated register offsets. Create a copy of the updated clock
code in hdmi_pll_8960.c, instead of rewriting it in hdmi_phy_8960.c
itself. This removes the need to place CONFIG_COMMON_CLOCK checks all
around, makes the code more legible, and also removes some old checkpatch
warnings with the original code.
The older hdmi pll clock ops in hdmi_phy_8960.c will be removed later. The
driver will use these until the HDMI PHY/PLL register offsets aren't
considered as separate domains (i.e. their offsets start from 0).

Create a PHY device that represents the TX PHY and PLL parts of the HDMI
block.
This makes management of PHY specific resources (regulators and clocks)
much easier, and makes the PHY and PLL usable independently. It also
simplifies the core HDMI driver, which currently assigns phy ops among
many other things.
The PHY driver implementation done here is very similar to the PHY driver
we already have for DSI.
Keep the old hdmi_phy_funcs ops for now. The driver will use these until
the HDMI PHY/PLL register offsets aren't considered as separate
domains (i.e. their offsets start from 0).
The driver doesn't use the common PHY framework for now. This is because
it's hard to map our ops with the ops provided by the framework. The
bindings used for this is the generic phy bindings. So, this can be
adapted to the PHY framework in the future, if possible.

Some platforms may not have a HPD gpio line to detect Hot Plug signal from
the connector. They need to rely only on reading REG_HDMI_HPD_INT_STATUS
for HPD.
Modify hdmi_connector_detect logic such that it checks for HPD only using
the status register if there is no HPD gpio.

Make gpio allocation and usage iterative by parsing the gpios on a given
platform from a list. This gives us flexibility over what all gpios exist
for a platform, whether they are input or output, and what value they
should be set to.
In particular, this will make HDMI on 8x96 platforms easier to integrate
with the driver, as it doesn't have a HPD gpio input to them. Also, it
cleans things up a bit.
We still use the legacy gpio api here, as we might need to backport this
driver to downstream kernels.

This supports 420 and 422 subsampling with 2 or 3 planes, tested with
modetest. It doesn't set up chroma subsampling position (which it
appears KMS doesn't deal with yet).

Previously, on every modeset we would allocate new display list
memory, recompute changed planes, write all of them to the new memory,
and pointed scanout at the new list (which will latch approximately at
the next line of scanout). We let
drm_atomic_helper_wait_for_vblanks() decide whether we needed to wait
for a vblank after a modeset before cleaning up the old state and
letting the next modeset proceed, and on legacy cursor updates we
wouldn't wait. If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.
Instead of making cursor updates wait for scanout to move to the new
display list area (which introduces significant cursor lag in X), we
just rewrite our current display list.
