Generic code maps TYPE_HARDWARE and TYPE_HW_CACHE to TYPE_RAW for a
first go, only if that fails it will try the actual type.

And x86 has the (first) CPU PMU has TYPE_RAW, on hybrid, it will
transparently pick the right actual PMU.

That said; given that this commit has been tagged twice now, I suppose I
should go revert it and we'll try again after a more thorough audit.
