ddr3: Fix SPD CRC calculation
Use the correct SPD size for crc calculation. sizeof(*spd) returns 4
while sizeof(spd_raw_data) returns the expected value of 256.
Fixes erroneous printing of "ERROR: SPD CRC failed!!!" in raminit log.
Verified by testing this code on Intel IvyBridge and Gigabyte GA-B75M-D3H.
