arm64: dts: mediatek: mt8195: Add missing gce-client-reg to mutex
[ Upstream commit 3b129949184a1251e6a42db714f6d68b75fabedd ]
Add the missing mediatek,gce-client-reg property to the mutex node to
allow it to use the GCE. This prevents the "can't parse gce-client-reg
property" error from being printed and should result in better
performance.
