Aaron Durbin 57686f8485 x86: unify amd and non-amd MTRR routines
The amd_mtrr.c file contains a copy of the fixed MTRR algorithm.
However, the AMD code needs to handle the RdMem and WrMem attribute
bits in the fixed MTRR MSRs. Instead of duplicating the code
with the one slight change introduce a Kconfig option,
X86_AMD_FIXED_MTRRS, which indicates that the RdMem and WrMem fields
need to be handled for writeback fixed MTRR ranges.

The order of how the AMD MTRR setup routine is maintained by providing
a x86_setup_fixed_mtrrs_no_enable() function which does not enable
the fixed MTRRs after setting them up. All Kconfig files which had a
Makefile that included amd/mtrr in the subdirs-y now have a default
X86_AMD_FIXED_MTRRS selection. There may be some overlap with the
agesa and socket code, but I didn't know the best way to tease out
the interdependency.
