x86, hibernate: Initialize mmu_cr4_features during boot
Restore the initialization of mmu_cr4_features during boot, which was
removed without comment in checkin e5f15b45ddf3afa2bbbb10c7ea34fb32b6de0a0e
x86: Cleanup highmap after brk is concluded
thereby breaking resume from hibernate. This restores previous
functionality in approximately the same place, and corrects the
reading of %cr4 on pre-CPUID hardware (%cr4 exists if and only if
CPUID is supported.)
However, part of the problem is that the hibernate suspend/resume
sequence should manage the save/restore of %cr4 explicitly.
