[RFC V2 6/6] arm64: dts: imx8mq: Split i.MX8MQ G1 and G2 with vpu-blk-ctrl

[Adam Ford]

With the Hantro G1 and G2 now setup to run independently, update
the device tree to enable it again.  This requires the vpu-blk-ctrl
node to be configured, and the clock-parents and clock-rates for
the various VPU's to be moved into the pgc_vpu because they cannot
get re-parented once enabled, and the pgc_vpu is the highest
in the chain.
