Right, the mmsys device is now the parent of the drm device.
Reviewed-by: Enric Balletbo i Serra
Also I tested drm with the patch applied and adding the gce client register to
my device-tree.

[PATCH] drm: mediatek: fix device passed to cmdq
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")
