x86: Add another set of MSR accessor functions

commit 22085a66c2fab6cf9b9393c056a3600a6b4735de upstream.

We very often need to set or clear a bit in an MSR as a result of doing
some sort of a hardware configuration. Add generic versions of that
repeated functionality in order to save us a bunch of duplicated code in
the early CPU vendor detection/config code.
