[PATCH 5/8] x86: remove dependencies on CONFIG_M... CPU options

From: Arnd Bergmann <arnd at arndb.de>

CPU specific features should generally be controlled by
CPU_SUP_xxx options rather than CONFIG_Mxxx, to allow
generic kernels to be built that work with all of them.

Replace the few options that don't follow this scheme
with checks on either CPU_SUP_xxx or X86_PAE by itself.
