[PATCH 0/3] Fixes for VF GuC version and guc_info debugfs

[Daniele Ceraolo Spurio]

The VF currently stores the negotiated GuC compatibility version in a
private VF struct, so all the runtime checks using the common struct in
guc->fw are not working as expected. We can fix this by copying the value
over.

This also partially fixes the guc_info debugfs, printing the correct
values for the wanted and found versions, but we do still need to stop
it from reading VF-unaccessible registers.

Note that this series is technically a v2 of [1], but the approach and
the patches themselves are changed enough that it seemed cleaner to
restart from v1.
