drm/amd/display: Program OTG vtotal min/max selectors unconditionally
OTG_V_TOTAL_MIN/MAX_SEL bits are required to be programmed to 1 if
writes to OTG timing registers need to be honoured. This is usually
needed only when freesync is active. However, SubVP + DRR requires that
we're able to change timing even without freesync being active (but
supported). By unconditionally writing this bit to 1, we remove an
unnecessary dependency so that DMCUB can change OTG timing whenever it wants.
