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
