[PATCH 0/3] Enable GuC opt-in features

[Daniele Ceraolo Spurio]

The GuC supports a H2G to opt-in to extra features on a per-VF basis.
We're interested in 2 of those features:

1 - Extended CAT error info (extra debug info)
2 - Dynamic ICS (optimization)

More details on what those do in the respective patches.

This series adds code to conditionally enable those features in both
native/PF and VF. Note however that 2 other requirements need to be
satisfied for them to fully take effect:
1 - for the VF enablement to actually work we need another series to
correnctly set the GuC compatibility version [1], but these patches can
be merged in parallel as there is no direct dependency in code.
2 - Dynamic ICS needs GuC 70.40.1 or newer, but the bump to 70.40.2
(from 70.36) is currently in flight [2].
