Some of the newer platforms use a bigger RSA key to authenticate the GuC,
which is provided to the HW via a ggtt-pinned object instead of mmio.

While doing the changes for this I've also spotted an inconsistency in
the error status of the fw on init failure, so I've added a path to fix
that as well.
