The GSC firmware, support for which is coming soon for Xe, has both a
release version (updated on every release) and a compatibility version
(update only on interface changes). The GuC has something similar, with
a global release version and a submission version (which is also known
as the VF compatibility version). The main difference is that for the
GuC we still want to check the driver requirement against the release
version, while for the GSC we'll need to check against the compatibility
version.
Instead of special casing the GSC, this patch reworks the FW logic so
that we store both versions at the uc_fw level for all binaries and we
allow checking against either of the versions. Initially, we'll use it
to support GSC, but the logic could be re-used to allow VFs to check
against the GuC compatibility version.
Note that the GSC version has 4 numbers (major, minor, hotfix, build),
so support for that has been added as part of the rework and will be
used in follow-up patches.
