Subject: [PATCH V4 05/11] dt-bindings: media: nxp, imx8mq-vpu: Split G1 and G2 nodes

The G1 and G2 are independent and separate decoder blocks
that are enabled by the vpu-blk-ctrl power-domain controller,
which now has a proper driver.

Because these blocks only share the power-domain, and can be
independently fused out, update the bindings to support separate
nodes for the G1 and G2 decoders with vpu-blk-ctrl power-domain
support.

The new DT + old kernel isn't a supported configuration.
