SoCs having mdp5 or dpu have identical tree like
device hierarchy where MDSS top level wrapper manages
common power resources for all child devices.
Subclass msm_mdss so that msm_mdss includes common defines
and mdp5/dpu mdss derivations to include any extensions.
Add mdss helper interface (msm_mdss_funcs) to msm_mdss
base for mdp5/dpu mdss specific implementation calls.
This change subclasses msm_mdss for mdp5, dpu specific

f9cb8d8d83 fixed various race conditions with CTL flush, in particular
flushing and sending the START signal before encoder state was updated.
But it did this a little too well in some cases that don't trigger
encoder->enable(), and CTL[n].FLUSH would never be set. When page flips
happen it would paper over the bug, since the first plag flip would
flush out the state to the hardware.
The issue could be reproduced with, for example, modetest (without the
'-v' argument).

There's a race between idling the engine and finishing off the last
tasklet (as we may kick the tasklets after declaring an individual
engine idle). However, since we do not need to access the device until
we try to submit to the ELSP register (processing the CSB just requires
normal CPU access to the HWSP, and when idle we should not need to
submit!) we can defer the assertion unto that point. The assertion is
still useful as it does verify that we do hold the longterm GT wakeref
taken from request allocation until request completion.

We make a decision at module load whether to use the GuC backend or not,
but lose that setup across set-wedge. Currently, the guc doesn't
override the engine->set_default_submission hook letting execlists sneak
back in temporarily on unwedging leading to an unbalanced park/unpark.
v2: Remove comment about switching back temporarily to execlists on
guc_submission_disable(). We currently only call disable on shutdown,
and plan to also call disable before suspend and reset, in which case we
will either restore guc submission or mark the driver as wedged, making
the reset back to execlists pointless.

It was originally introduced following the VESA spec in order to validate PSR.
However we found so many issues around sink_crc that instead of helping PSR
development it only brought another layer of trouble to the table.
So, sink_crc has been a black whole for us in question of time, effort and hope.
First of the problems is that HW statement is clear: "Do not attempt to use
aux communication with PSR enabled". So the main reason behind sink_crc is
already compromised.
For a while we had hope on the aux-mutex could workaround this problem on SKL+
platforms, but that mutex was not reliable, not tested,
and we shouldn't use according to HW engineers.
Also, nor source, nor sink designed and implemented the sink_crc to be used like
we are trying to use here.
Well, the sink side of things is also apparently not prepared for this
case. Each panel that we tried seemed to have a different behavior with same
code and same source.
So, for all the time we lost on trying to ducktape all these different issues
I believe it is now time to move PSR to a more reliable validation.
Maybe not a perfect one as we dreamed for this sink_crc, but at least more
reliable.
