cpu/x86: Support CPUs without rdmsr/wrmsr instructions
Quark does not support the rdmsr and wrmsr instructions. In this case
use a SOC specific routine to support the setting of the MTRRs. Migrate
the code from FSP 1.1 to be x86 CPU common.
Since all rdmsr/wrmsr accesses are being converted, fix the build
failure for quark in lib/reg_script.c. Move the soc_msr_x routines and
their depencies from romstage/mtrr.c to reg_access.c.
TEST=Build and run on Galileo Gen2
