Revert "x86/PAT: Fix Xorg regression on CPUs that don't support PAT"
This reverts commit cbed27cdf0e3f7ea3b2259e86b9e34df02be3fe4.
As Andy Lutomirski observed:
"I think this patch is bogus. pat_enabled() sure looks like it's
supposed to return true if PAT is *enabled*, and these days PAT is
'enabled' even if there's no HW PAT support."
