The upcoming unified GuC FW will require us to send video engine enable
masks to GuC for its initialization.
For consistency, just set the runtime_info enable masks for all gens.
We'll then be able to directly use those in the GuC setup

D'oh!
Thanks for catching this, GuC just ignores the higher bits and didn't
complain, so I missed it.
Having demonstrated it's a simple mapping, do we need to store it
separately?
#define VDBOX_MASK(info) \
(((info)->engine_mask & \
GENMASK(VCS0 + I915_MAX_VCS - 1, VCS0)) >> VCS0)
LGTM, will do the changes.
