x86/mm/pat: Revert 'Adjust default caching mode translation tables'
Toshi explains:
"No, the default values need to be set to the fallback types,
i.e. minimal supported mode. For WC and WT, UC is the fallback type.
When PAT is disabled, pat_init() does update the tables below to
enable WT per the default BIOS setup. However, when PAT is enabled,
but CPU has PAT -errata, WT falls back to UC per the default values."
