[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 Reviewed-by: Alvin Lee <alvin.lee2@amd.com> Acked-by: Alex Hung <alex.hung@amd.com> Signed-off-by: Ethan Bitnun <etbitnun@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
