arm64: dts: mediatek: mt8195: Add missing gce-client-reg to vpp/vdosys

Add the missing mediatek,gce-client-reg property to the vppsys and
vdosys nodes to allow them to use the GCE. This prevents the "can't
parse gce-client-reg property" error from being printed and should
result in better performance.
