drm device is now probed from mmsys. We need to use mmsys device to get gce
nodes. Fix following errors:
[ 0.740068] mediatek-drm mediatek-drm.1.auto: error -2 can't parse
gce-client-reg property (0)
[ 0.748721] mediatek-drm mediatek-drm.1.auto: error -2 can't parse
gce-client-reg property (0)
...
[ 2.659645] mediatek-drm mediatek-drm.1.auto: failed to request channel
[ 2.666270] mediatek-drm mediatek-drm.1.auto: failed to request channel
Fixes: 1d367541aded ("soc / drm: mediatek: Fix mediatek-drm device probing")
