google/link: fix detection of dimm on channel 1
Changes to the sandybridge memory init code (both MRC
and native) now require SPD data on all populated channels
in order for dimms to be detected properly, so copy
spd_data[0] to spd_data[2], as LINK always has 2
channels of memory down.
Test: boot google/link, observe onboard RAM correctly
detected on both channels
