arm64: dts: rockchip: Add missing power-domains for rk356x vop_mmu

Browse Source 
[ Upstream commit 9d42c3ee3c ]

The iommu@fe043e00 on RK356x SoC shares the VOP power domain, but the
power-domains property was not provided when the node has been added.

The consequence is that an attempt to reload the rockchipdrm module will
freeze the entire system.  That is because on probe time,
pm_runtime_get_suppliers() gets called for vop@fe040000, which blocks
when pm_runtime_get_sync() is being invoked for iommu@fe043e00.

Fix the issue by adding the missing property.
