MFamd64: Use initializecpu() to set various model-specific registers on

AP startup and AP resume (it was already used for BSP startup and BSP
resume).
- Split code to do one-time probing of cache properties out of
  initializecpu() and into initializecpucache().  This is called once on
  the BSP during boot.
- Move enable_sse() into initializecpu().
- Call initializecpu() for AP startup instead of enable_sse() and
  manually frobbing MSR_EFER to enable PG_NX.
- Call initializecpu() when an AP resumes.  In theory this will now
  properly re-enable PG_NX in MSR_EFER when resuming a PAE kernel on
  APs.
