Venki Pallipadi 80c5e73d60 x86: fix Xorg startup/shutdown slowdown with PAT
Rene Herman reported significant Xorg startup/shutdown slowdown due
to PAT. It turns out that the memtype list has thousands of entries.

Add cached_entry to list add routine, in order to speed up the
lookup for sequential reserve_memtype calls.
