Track available hw resources using a common data structure in
the sde_rm object and pass available hw resource info to
interface drivers to make informed decisions in preparing
or filtering display modes.

Create a data structure to maintain available hardware resources
and track capabilities. This data structure is used to send
the current available resources and caps information to
connector ops get_mode_info, get_modes and validate_mode to
process the display mode.

There is a race condition between sdm thread and display thread, when
sdm thread may be accessing the mode_info field while duplicating the
connector state, display thread may be updating the current mode info.
This would lead to the next commit using invalid mode and could cause
wrong hw configuration.
This change removes copying the mode_info in encoder struct while
atomic check phase and also removes accessing the connector mode_info
during mode_set. The encoder struct is now updated at the mode_set
with the cached connector mode.

The right_mixer and hist_en checks in LTM hist disable function are
not valid for dual display use cases, since in dual display use cases,
right_mixer will always be NULL.
When device enters suspend state, hist_en will be set to false in
sde_cp_crtc_suspend(), and together with the right_mixer check,
it will block the ltm buffer lists from resetting and cause LTM has
no buffers to use after resume.

wr_ptr_irq timeout signifies that the MDP is stuck
on either the current or previous frame. Handle
ctl reset and fence signalling as part of this
timeout handling. This logic would help to recover
the HW faster in case of posted-start.

SDE curently uses two different bw thresholds, depending on
video and command mode panels. The lower threshold that was
being used with video mode caused perf check to fail, even
though it was still a valid functional use case. The driver
should always use the higher max bandwidth when checking
core crtc performance.

SDE RSC does not need to wait for vsync during
dms. It was removed unintentionally with commit
a74d2cf7fa ("disp: msm: add runtime_pm ops
support in drm driver"). However, Panel mode
switch still needs vsync wait based on
recommendation. This change fixes vsync wait
for both cases.

The dp sink explicitly states the numbers of
slices it can support. When calculating the
number of slices for dsc configuration, ensure
that the sink supports the calculated number of
slices.
If the sink does not support the calculated
number of slices, keep rechecking sink support
for the subsequent slice increment, until we
reach the highest number of slices possible
according to the dp spec. If no compatible
sink slice support is found, do not enable dsc.
