drm/amd/display: limit the v_startup workaround to ASICs older than DCN3.1

Browse source

Since, calling dcn20_adjust_freesync_v_startup() on DCN3.1+ ASICs
can cause the display to flicker and underflow to occur, we shouldn't
call it for them. So, ensure that the DCN version is less than
DCN_VERSION_3_1 before calling dcn20_adjust_freesync_v_startup().
