Subject: [PATCH] x86: Relegate CONFIG_PAT to EMBEDDED

PAT support (which got added to CPUs over 10 years ago) is no longer
really optional in that more and more things are depending on PAT
just working, including newer versions of X. Having this as a regular
config option just no longer makes sense.

This patch relegates CONFIG_PAT to the EMBEDDED category, in the hope
to eventually completely retire it.
