Pallipadi, Venkatesh 9e41a49aab x86, pat: Migrate to rbtree only backend for pat memtype management
Move pat backend to fully rbtree based implementation from the existing
rbtree and linked list hybrid.

New rbtree based solution uses interval trees (augmented rbtrees) in
order to store the PAT ranges. The new code seprates out the pat backend
to pat_rbtree.c file, making is cleaner. The change also makes the PAT
lookup, reserve and free operations more optimal, as we don't have to
traverse linear linked list of few tens of entries in normal case.
