nb/intel/sandybridge/raminit: always use mrccache
Always use MRC cache if possible. Added a CRC16 array to make sure the DIMMs haven't been replaced. In case one of the CRC's doesn't match, start normal RAM training. Use new fallback in case of broken mrc cache. Test system: * Gigabyte GA-B75M-D3H * Intel Pentium CPU G2130 Test result: The system boots a lot faster using the MRC cache. On swapping DIMMs the CRC16 doesn't match and normal ram training is started.
