x86, microcode: Reload microcode on resume

commit fbae4ba8c4a387e306adc9c710e5c225cece7678 upstream.

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.
