nb/intel/sandybridge: Allow to ignore XMP voltage

Native raminit only supports 1.5V operation, but there are DIMMs which
request 1.65V operation in XMP profiles. Add an option to force XMP to
be used when the requested voltage isn't supported, which will run the
DIMMs at 1.5V with XMP timings. Consider this to be overclocking.
