soc/intel/tigerlake: fix call to print_spd_info()

Pointer passed to print_spd_info() from meminit.c needs to be
dereferenced first, so this change dereferences it.

BUG=b:154352883
TEST="emerge-volteer coreboot chromeos-bootimage", flash and boot
volteer, login to kernel and execute the following cbmem command:
  localhost ~ # cbmem -c | grep LPDDR4X
and verify it returns "SPD: module type is LPDDR4X"
