Sometimes the GuC load is slower that it should be. For end users,
that usually means some kind of thermal throttling issue. Internally,
there can be any number of bugs that cause it. So don't completely
fail to load, just cope with it and report the problem.

v2: Revert include order (review feedback from Lucas)
v3: Remove '_sysfs' from throttle file names and keep limit query in
the same file rather than moving elsewhere (review feedback from
Rodrigo). Fix the reporting of requested vs granted frequencies
(review feedback from Badal).
v4: Manually code the loop timeout/condition checking because helper
functions are not allowed (review feedback from Lucas/Rodrigo)
v5: Correct a #include, improve the comments even more, add units to a
#define (review feedback from Lucas).
v6: Fix typo in _wait32_not (review feedback from Lucas) and rebase.
