- Only reserve APIC memory on x86

- Don't reserve 32 pages for VGA registers -- deprecated since 11917, 4 years ago
- Use KeNumberProcessors instead of MAXIMUM_PROCESSORS when mapping the PCRs
- Remove MmInitMemoryAreas, a nop since revision 1093, 8 years ago
- Remove unused KeMemoryMapRangeCount/KeMemoryMap
