[Why]
Due to the freesync power optimization increasing vtotal, the driver
believes that MPO is supported. MPO is turned on. Freesync then
exits, MPO can no longer be supported and immediate flip fails. This
causes corruption on the panel.
[How]
Avoid the freesync optimization when doing validation so in the case
freesync exits, driver can still support the configuration.

[Why]
Currently, when full p-state changes are not supported, DLG parameters
are calculated for no p-state support at all. However, we are required
to always support dummy p-state changes, so we should instead calculate
DLG based on dummy p-state latency when full p-state is unsupported.
This behaviour already exists for DCN2.
[How]
- move DLG calculation inside WM calculation
- if p-state unsupported, do not recalculate for set A, instead copy from
set C, and perform DLG calculation with dummy p-state latency

[Why]
Register definitions are asic-specific, so functions that use registers of
a particular asic should be static, to be exposed in asic-specific function
pointer structures.
[How]
- make register-definition-using functions static
- make some functions non-static, for future use
- remove duplicate function definition
