Subject: [RFC V2 1/2] media: hantro: Add support for i.MX8M Mini

The i.MX8M Mini has a similar implementation of the Hantro G1 and
G2 decoders, but the Mini uses the vpu-blk-ctrl for handling the
VPU resets through the power domain system.  As such, there are
functions present in the 8MQ that are not applicable to the Mini
which requires the driver to have a different compatible flags.
