25cdb9c868 x86/microcode/intel: Fish out the stashed microcode for the BSP
I'm such a moron! The simple solution of saving the BSP patch
for use on resume was too simple (and wrong!), hint:
sizeof(struct microcode_intel).

What needs to be done instead is to fish out the microcode patch
we have stashed previously and apply that on the BSP in case the
late loader hasn't been utilized.

So do that instead.

fbae4ba8c4 x86, microcode: Reload microcode on resume
Normally, we do reapply microcode on resume. However, in the cases where
that microcode comes from the early loader and the late loader hasn't
been utilized yet, there's no easy way for us to go and apply the patch
applied during boot by the early loader.

Thus, reuse the patch stashed by the early loader for the BSP.

f99b45c3c2 x86, microcode, intel: Fix typos
Fix some typos. One of them was in a struct name, fortunately harmless
because it happened on a "sizeof(struct foo*)" construction.

bad5fa631f x86, microcode: Move to a proper location
We've grown a bunch of microcode loader files all prefixed with
"microcode_". They should be under cpu/ because this is strictly
CPU-related functionality so do that and drop the prefix since they're
in their own directory now which gives that prefix. :)

While at it, drop MICROCODE_INTEL_LIB config item and stash the
functionality under CONFIG_MICROCODE_INTEL as it was its only user.
