ReactOS Portable Systems Group 128aefcd63 - Rewrite MmMapIoSpace and MmUnmapIoSpace to use System PTEs instead.
- Much faster and cleaner (will be even faster when System PTE allocation is optimized).
- Better handling of esoteric caching options, especially relevant for ARM.
  - Handled through the MiPlatformCacheAttributes, which should be defined differently for each platform (TODO).
    - Handles both I/O (device) and RAM physical memory.
- Correct flushing of CPU caches (not a big deal on x86, but matters on ARM).
