drm/amd/display: Find max flickerless instant vtotal delta

Browse Source 
[WHAT & HOW]
 - Populate dml 2 callback with get_max_flickerless_instant_vtotal_increase
 - Use long long when necessary to prevent overflow
 - Add asic specific default values, currently disabled by
   default for every asic
 - Use the pre-existing debug option to protect the call to
   get_max_flickerless_instant_vtotal_increase
