[Why]
Previously the 'dsc_bits_per_comp' enumeration was defined in individual
.c files, making it unavailable for other files that may need it.
[How]
The 'dsc_bits_per_comp' enumeration has been relocated to a common header
file.

[WHY]
When system exits idle state followed by enabling the display,
DSC memory may still be forced in a deep sleep or shutdown state.
Intermittent DSC corruption is seen when display is visible.
[HOW]
When DSC is enabled, reset dsc memory to force and disable status.

[why]
Switching between DSC clock or disable DSC block are not double buffered update.
Corruption is observed if these updates happen before DSC double buffered
disconnection.
[how]
Move DSC disable and refclk reset to post unlock update. Wait for DSC double buffered
disconnection and all mpccs are disconnected before reset DSC clock.
