drm/amd/display: Updated optc401_set_drr to use dcn401 functions

drm/amd/display: Updated optc401_set_drr to use dcn401 functions

why:
optc_401_set_drr was using an old optc3 function to update vtotal min and max,
causing crashes when disabling FAMS2

how:
Updated dcn401 to point to opt401 function for vtotal updates. This version of
the function has FAMS2 logic that allows for FAMS2 to be disabled.
