Aaron Durbin 2b72e6bdfd util/x86/x86_page_tables: update PAT mapping to match linux
The linux kernel uses the following mapping for PAT entries:
  PTE encoding:
      PAT
      |PCD
      ||PWT  PAT
      |||    slot
      000    0    WB : _PAGE_CACHE_MODE_WB
      001    1    WC : _PAGE_CACHE_MODE_WC
      010    2    UC-: _PAGE_CACHE_MODE_UC_MINUS
      011    3    UC : _PAGE_CACHE_MODE_UC
      100    4    WB : Reserved
      101    5    WP : _PAGE_CACHE_MODE_WP
      110    6    UC-: Reserved
      111    7    WT : _PAGE_CACHE_MODE_WT

Update the page table generator to match what the linux kernel is
using. This just makes things consistent with linux.
