arm64: dts: rockchip: px30: fix enc and dec run at the same issue

Due to the particularity of the px30 iommu, it is necessary to configure
the grf to switch iommu.
So need to configure rockchip,shootdown-entire to prevent a case from
happening: when one device is running, the task of another device
operates iommu when doing map.

This commit relies on the following commit:
commit 3b67ff56d6 ("video: rockchip: mpp: add iommu flush tlb before hw run for px30")
