cpu/intel/socket_FCBGA559: Use the non-evict cache as ram setup
Pineview CPUs support a non-eviction mode that ought to be used
during cache as ram setup.
This assumes that all atoms that need to set a special register to
enable L2 cache are socketed and hence uses a static Kconfig option
to set that MSR on affected CPUs.
Tested on Foxconn D41S, still boots.
