[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 Signed-off-by: Joshua Aberback <joshua.aberback@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
