nb/intel/sandybridge/raminit: Fix SMBIOS 17 bus width

The bus width has to be encoded where the lower 3 bits are the bus width
in multiple of 8 and the following two bits give the error checking
bits in multiple of 8.
Hardcode to 64 bit as done on haswell.
TODO: Make it dynamic once there's ECC support.
