Subject: [PATCH v4 03/17] media: venus: Introduce VPU version distinction

The Video Processing Unit hardware version is the differentiator, based
on which the video driver should decide which code paths to take.

Up until now, we've relied on HFI versions instead, 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.
