[Why]
Current fullscreen check in SPL using dm_helpers is out-of-sync
with dc state. This causes an issue during minimal transition
where we pick an invalid intermediate state because the pre and
post fullscreen status are different.
[How]
Add sharpening_required flag to dc_stream_state. Use this flag to
indicate if we are in fullscreen or not. Propagate flag to SPL for
fullscreen status. Remove workaround in DML

[Why]
We want to clean up unnecessary asserts, one of which is an assert in
resource_is_pipe_type that fires if a pipe has no stream and still has
pointers to other pipes ("dangling state"). This gets hit because pipes
are not properly cleaned up in reset_back_end_for_pipe. When resetting a
pipe, the existing MPCC / ODM combine pointers are no longer valid,
especially when we put ODM in bypass.
[How]
- reset pipe pointers in reset_back_end_for_pipe
- remove useless code to avoid confusion

There is a known HW bug that causes the internal 3DLUT fetch signal to

stays up after OTG unlock.
[How]
Set the 3DLUT_ENABLE bit immediately before and after the unlock. Also
use VUPDATE_KEEPOUT to prevent lock transition in the region between
VSTARTUP and VREADY, which could cause issues with this WA sequence.
Also including misc. 3DLUT DMA-related sequence fixes to address a few

[Why]
Since the surface/stream update flags aren't cleared after applying
updates, those same updates may be applied again in a future call to
update surfaces/streams for surfaces/streams that aren't actually part
of that update (i.e. applying an update for one surface/stream can
trigger unintended programming on a different surface/stream).
For example, when an update results in a call to
program_front_end_for_ctx, that function may call program_pipe on all
pipes. If there are surface update flags that were never cleared on the
surface some pipe is attached to, then the same update will be
programmed again.
[How]
Clear the surface and stream update flags after applying the updates.
