drm/amd/display: fix mode scaling (RMX_.*)
As made mention of in commit 4a2df0d1f28e ("drm/amd/display: Fixed
non-native modes not lighting up"), we shouldn't call
drm_mode_set_crtcinfo() once the crtc timings have been decided. Since,
it can cause settings to be unintentionally overwritten. So, since
dm_state is never NULL now, we can use old_stream to determine if we
should call drm_mode_set_crtcinfo() because we only need to set the crtc
timing parameters for entirely new streams.
