Add compile-time defaults to some K8 CMOS options in case they're absent in CMOS
This affects the CMOS options iommu, ECC_memory, max_mem_clock,
hw_scrubber, interleave_chip_selects.
If they're absent in cmos.layout, a Kconfig value is used if it exists,
or a hardcoded default otherwise.
[Patrick: I changed the ramstage CMOS handling a bit, and dropped the
reliance of hw_scrubber on ECC RAM, as it has nothing to do with it -
it's the cache that's being scrubbed here.]
