drm/amd/display: Plumb MRQ programming out of DML for dml2_1
[Why]
If the MRQ is present then these fields are also required to be
plumbed out to the requestor for programming.
[How]
Pipe the fields out through rq_dlg_get_rq_reg.
The implementation follows the previous generation in dml2_0 for DCN35
but adjusted for the new helpers and coding style of dml2_1.
