[RFC 0/5] Split iMX8MQ Hantro VPU into G1 and G2 with blk-ctrl support

[Adam Ford]

Currently, the VPU in the i.MQ8MQ is appearing as one codec, but in reality, it's
two IP blocks called G1 and G2.  There is initialization code in VPU code to
pull some clocks, resets and other features which has been integrated into
the vpu-blk-ctrl for the i.MX8M Mini and a similar method can be used to make
the VPU codec's operate as stand-alone cores without having to know the details
of each other or the quirks unique to the i.MX8MQ, so the remaining code can be
left more generic.

This series was started by Lucas Stach, and picked up by me so some patches have
his s-o-b and mine where I might have changed a few minor items.  It's in an RFC state
because the G2 VP9 operations appear to hang, but the parent code from which I started doesn't
appear to show VP9 support, and it looks like it should.

since the g-streamer and media trees are in a constant state of change, this series is based on
git://linuxtv.org/hverkuil/media_tree.git for-v5.17e
