Vblank refcount can reach out of sync with below case
1. event_thread triggers the vblank_enable
2. commit_thread triggers the modeset
2.a modeset resets the vblank refcount with mode_set
3. event_thread triggers the vblank_disable
Event 2.a resets the vblank refcount and vblank disable
request after 2.a is going to fail. This can be fixed
by avoiding concurrency between mode_set call and vblank
request.

VM switches during TUI usecase are expected to be seamless i.e without
display reset. In SDE language, this translates to respective display
drivers not tearing down the HW pipeline while releasing the HW.
In Primary VM, this taken care by keeping the DRM pipeline alive when
TUI is active.
In Trusted VM, since the client creates and destroys the display per
session, checks are needed to bypass the physical encoder disable(s).

Current SDE driver allows staging of rect1 only configuration. When a
real plane is disabled sspp multi rect configuration is not updated.
This can lead to iommu faults and ping pong timeouts as framebuffer of
disabled plane is unmapped. This change fixes it by updating multi rect
config accordingly when a plane is disabled.

Trusted VM will be assigned MDSS HW access dynamically only on TUI
use case start boundary. So, any HW access during the boot sequence
will result in stage2 faults. But SDE driver initializes few HW
blocks during the boot up sequence. This change fixes them by either
skipping those accesses, if those registers expected to be programmed
by the Primary VM or postponing those accesses until the HW is
assigned.

Existing cwb enable detection logic relies on
crtc id matching with each encoder->crtc. This
may not be available on first power on commit
because it updated after encoder_atomic_check
call. This patch fixes the cwb enable detection
logic by checking the encoder_mask on crtc_state.
It also fixes the cwb concurrency with mode_set
and secure display.

Current dp_mst_bridge has variables that are accessed by both
check phase and commit phase, which causes racing issues. This
change will add private state to dp_mst_bridge to separate check
phase and commit phase.
Furthermore, this change is a partial rollback of commit 2446602565ec
("drm/msm/dp: add private state to dp_mst_bridge") where active_enc_cnt
is removed. In this change we retain the encoder availability check in
mode_valid.

Currently DP driver determines if a mode is DSC capable
based on a DTSI entry and the required number of DSC
to support it. This approach does not scale when there
is an overlap in DSC requirement between DSI displays
and external DP display, thus causing one of the display to
report modes that cannot be supported.
This change compares the resources reserved for DP driver
calculated at initialization time and the currently available
ones to determine the correct number of resources that DP driver
can use. It also adds DSC and topology filtering logic and moves
DSC hardware specific from DP driver to SDE driver.
