[Why&How]
Virtual monitors are now being validated during set_mode.
Virtual monitors should not undergo backend validation,
as the backend is intended only for physical monitors.
Virtual sinks have no real backend part information and
should be excluded from this validation.

[Why]
mcache allocation programming is not part of DML's core responsibilities.
Keeping this logic in DML leads to poor separation of concerns and complicates maintenance.
[How]
Refactored code to move mcache parameter preparation and mcache ID assignment
into the resource file.

[WHY]
Triplebuffer should be programmed on all pipes.
Some code assumed it only needed to be called on top
pipe, but as the HWSS function does not account
for that, it must be called on every pipe.
[HOW]
Remove condition to not program triplebuffer
on non-top/next pipe. Call the function
unconditionally on all pipes.

[why&how]
It is possible for an update to acquire otg lock and begin programming
while the previous update has not completed and its values have not
latched. The correct way to go about this is to wait until the vupdate
pulses so we can be sure that previous updates have latched and we can
continue with the current update pipe programming, otherwise during
consecutive full updates we will have corruption flash on the screen.
The corruption flash occurs specifically on configs that require odm
combine, and its local to a specific pipe (will not flash across whole
screen). This ticket is across the otg slave, but it may also appear
across master.

[Why]
This array was initially defined as size 50. There were array overflow
issues so the size was increased to 100. To ensure such issues are
avoided in the future, the size should be set based on the possible
contents instead of an arbitrary value.
[How]
- upper bound, assume every update occurs on max number of pipes
- define array sizes for function parameters, for static analysis

[WHY]
When the system powers up eDP with external monitors in seamless boot
sequence, stutter get enabled before TTU and HUBP registers being
programmed, which resulting in underflow.
[HOW]
Enable TTU in hubp_init.
Change the sequence that do not perpare_bandwidth and optimize_bandwidth
while having seamless boot streams.

[Why]
Have the need to specify the CRC window on specific CRC engine.
dc_stream_configure_crc() today calculates CRC on crc engine 0 only and always
resets CRC engine at first.
[How]
Add index parameter to dc_stream_configure_crc() for selecting the desired crc
engine. Additionally, add another parameter to specify whether to skip the
default reset of crc engine.
