A failure to load the GuC is occasionally observed where the GuC log
actually showed that the GuC had loaded just fine. The implication
being that the load just took ever so slightly longer than the 200ms
timeout. Given that the actual time should be tens of milliseconds at
the slowest, this should never happen. So far the issue has generally
been caused by a bad IFWI resulting in low frequencies during boot
(depsite the KMD requesting max frequency). However, the issue seems
to happen more often than one would like.

So a) increase the timeout so that the user still gets a working
system even in the case of slow load. And b) report the frequency
during the load to see if that is the case of the slow down.

v2: Reduce timeout in non-debug builds, add references (Daniele)
