drm/amd/display: Block FPO According to Luminance Delta

Browse source

[Description]
 - Block FPO if the max stretch refresh rate is low enough
   to cause a flicker by storing the maximum safe refresh
   decrease from nominal in stream.
 - Brought over various Freesync Luminance functions to dc. Use these
   new functions to block fpo if we will flicker.
 - Generalized increase/reduce dependent functions to reduce code clutter
   and allow for easier use.
 - Added a debug option to enable the feature. Disabled by default.
