mb/samsung/lumpy: Move onboard SPD to second channel
Move the onboard SPD to second channel as native raminit does and workaround
mrc expecations in northbridge code.
Required to move pei data to devicetree and to use the same code for mrc and
native raminit.
Tested on Lenovo T520:
Other fields then spd_data[0] are ignored.
