Subject: [PATCH 02/18] media: venus: Introduce VPU version distinction

The Video Processing Unit hardware version is the differentiator,
based on which we should decide which code paths to take in hw
init. Up until now, we've relied on HFI versions, but that was
just a happy accident between recent SoCs. Add a field in the
res struct and add correlated definitions that will be used to
account for the aforementioned differences.
