This uses the EDID info from the Sony PlayStation VR headset,
when connected directly, to mark it as non-desktop.
Since the connection box (product id b403) defaults to HDMI
pass-through to the TV, it is not marked as non-desktop.

amdgpu_dm_display_resume is now called from dm_resume to
unify DAL resume call into a single function call
There is no more need to separately call 2 resume functions
for DM.
Initially they were separated to resume display state after
cursor is pinned. But because there is no longer any corruption
with the cursor - the calls can be merged into one function hook.

i965 and g4x still have the pipe select bits in the plane control
registers, they're just hardcoded to select a specific pipe. However
plane C on i965 can still move between the pipes, thus we should
program the pipe select bits on i965 if we want to expose plane C
some day.
Since there is no harm in programming the bits on any plane on
i965/g4x let's just always set them. This will also make our
pre-computed register value match what the hardware register
would read, should we want to cross check the two.

G4x cursor control registers still allow us to write to the pipe select
bits even though cursors are supposed to be fixed to a specific pipe.
Bspec tells us that we should only ever write 0 to these bits. Let's
follow that recommendation. On ilk+ the bits become hardwired to 0.
Also looks like ICL repurposes these bits for some other use, so
we had better stop setting them to bogus values there.

Add some compile time assrts to the frontbuffer tracking to make sure
that we have enough bits per pipe to cover all the planes, and that we
have enough total bits to cover all the planes across all pipes.
We'll ignore any potential clash between the overlay bit and the
plane bits because that will allow us to keep using a total of 32
bits for the foreseeable future.
While at it change the macros to use BIT() and GENMASK(). The latter
gets rid of the hardcoded 0xff and thus means we can change the
number of bits per pipe by just changing
INTEL_FRONTBUFFER_BITS_PER_PIPE.

Newer DSI host controllers (SDM845 in particular) require a new clock
called byte_intf_clk. A recent patch tried to add this as an optional
clock, but it still set 'ret' to an error number if it didn't find it.
This breaks the host's probe for all previous DSI host versions.
Instead of setting this up as an optional clock, try to get the clock
only for the DSI version that supports it.

The number and type of firmware files required differs for each
target. Instead of using a fixed struct member for each possible
firmware file use a generic list of files that should be loaded
on boot. Use some semi-target specific enums to help each target

drm_mm_init() takes the start and length of the intended virtual
memory address region but the msm code is passing the end of
the region instead. That would work out if the region started
at 0 but it doesn't so the top of the region sneaks above the
32 bit boundary which won't work because the driver doesn't
support 64 bit addresses for the GPU yet.

DSI6G v2.0+ blocks have a new clock input to them called
byte_intf_clk. It's rate is to be set as byte_clk / 2.
Within the clock controller (CC) subsystem, this clock is a
child/descendant of the byte_clk.
Set it up as an optional clock in the DSI host driver. Make sure
that we enable/set its rate only after we configure byte_clk.
This is required for the ancestor clocks in the CC to be
configured correctly.
