Subject: drm/amd/display: Fix disable DSC logic in the DIO code
Git-commit: fe674c0b6f5382b7c377ca2c418c26dd78b428b4
Patch-mainline: v6.1-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849
[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
