From: Eric Bernstein <eric.bernstein at amd.com>

[Why]
In DIO stream encoder, definition of DP_DSC_MODE is changed (only
enable/disable) In OPTC, OTG_SET_V_TOTAL_MIN_MASK_EN is removed (same as
DCN3.1)

[How]
In DIO stream encoder, update enc32_dp_set_dsc_config(). In OPTC, use
DCN3.1 version for function interfaces .set_vrr_m_const and .set_drr
