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.

The single "port" refcount has been split in 2 on 5.4. MST sim
layer is only getting the topology refcount but never initializes
or obtains references for the memory allocated for this port.
Add the new refcount logic required on 5.4 to MST sim layer.

QSEED scalar block HW revision is constant for a given MDSS revision.

fetch halt check completely because it was only done for
master plane without buffer flip usecase. AXI fetch halt
provides similar functionality during idle power collapse

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.

During transition to cwb, kthread initialisation has to
be done for the corresponding encoder off work so that
the correct worker thread is used for this particular
work. There can be scenarios where a cwb commit is
received after a writeback session and the worker
associated with the off work is still assigned to
old crtc's worker resulting in a mismatch when
this work is queued. Add support to handle such
scenarios.

Currently during rm_release, drm_conn is available only if connector
and encoder are bound together. If a test_only commit occurs
before a non-blocking modeset commit, this bound is uncertain.
The resources allocated by test_only commit will not be released
and leads to resource allocation failures for the consequent
commits. Add changes to modify this by checking for the encoder
attached to sde_connector which happens during bootup.
