This change fixes the vblank wait after system cache read mode
update. Without this change the wait does not happen since there is
no pending kickoff. This change uses encoder api to flush the
configuration and explicitly waits for vblank.

Clone WB encoder disable before posted start commit
trigger adds wb_wait delay in current frame trigger
sequence. This adds 1 frame jank if CWB enable/disable
path exercised periodically like 100ms or 200ms. This
change delays CWB encoder disable after frame trigger
and vsync/wr_ptr wait to avoid jank issue.

Allow for overriding color processing features that normally uses
DSPP flush to use LM flush instead. This is required on targets
where some of the DSPP features have been tied to LM flush bits.
This changes adds a field in color processing node to track if the
override is needed and enables LM flush override for rounded corner
on target requiring it.

Trusted VM adapts splash handoff path to acquire the same
set of HW blocks the tui display was using in the primary VM
before switching out.
To use the splash handoff path, Trusted VM should add an
additional vote to the PM so that refcounts will be remain
balanced after the splash path cleanup at the completion
of the first valid commit.
This change adds the needed vote and as a result cleans up
explicit voting from trusted vm commit paths.

When resuming the video session from a source initiated power down, the
dp_display driver is doing a link probe again to override the previous
link information parameters. The link_probe is not accurately capturing
all the sink capabilities resulting in the link getting trained at a
different rate when resuming from a PM suspend or a secure display
session. The HBR3 support is indicated in the extended capabilities
DPCD registers which is not considered in the upstream link probe
implementation.
This change will remove the drm_dp_link_probe function from the DP
driver because it is not capturing the accurate DP sink capabilities.

Fix the check for uneven split across LMs when destination
scaler is used and reject the use-case since this is not
supported by the driver. This can happen if an odd-value
for the horizontal width is being split across 2 mixers.
The existing check was broken since it uses pass-by-value
with a zero initialized value that callee tries to update
while iterating over the DS configurations. Use pass-by-
reference with the previous DS configuration, if available,
instead of just 0 values so the proper comparisons can take
place.

functionality was controlled via an overloaded feature flag
which is used to enable INTF tear-check ops (also added in DPU
5.x). External displays support INTF_STATUS but have no use for
any tear-check functions. Separate these features so they can be
enabled individually on the interfaces which support them.
