media: hantro: Allow i.MX8MQ G1 and G2 to run independently

The VPU in the i.MX8MQ is really the combination of Hantro G1 and
Hantro G2. With the updated vpu-blk-ctrl, the power domains system
can enable and disable them separately as well as pull them out of
reset. This simplifies the code and lets them run independently
while still retaining backwards compatibility with older device
trees for those using G1.
