drivers/intel/fsp2_0/memory_init: check if UPD struct has expected size

If the UPD size in coreboot sizes mismatches the one from the FSP-M
binary, we're running into trouble. If the expected size is smaller than
the UPD size the FSP provides, call die(), since the target buffer isn't
large enough so only the beginning of the UPD defaults from the FSP will
get copied into the buffer. We ran into the issue in soc/amd/cezanne,
where the UPD struct in coreboot was smaller than the one in the FSP, so
the defaults didn't get completely copied.

TEST=Mandolin still boots.
