drm/amd/display: Set Pipe Unlock Order Outside of HWSEQ

[Why]
Current pipe unlock order set within dcn401_interdependent_update_lock.
Separate the logic from the functionality to allow for unit testing
and make it easier to debug.

[How]
Add a flag to indicate if a pipe unlock order should be set.
Create function to determine unlock order.
Indicate which pipes should be unlocked first using
array stored in dc scratch memory.
Pipes indicated in array can be unlocked in any order.
