This change causes a freeze during boot on an RPL-UR that does not have
the memory part string in the CBI.

BUG=b:296353047
BRANCH=firmware-brya-14505.B
TEST='emerge-brya coreboot chromeos-bootimage', flash and boot
problematic DUT to kernel.

This reverts commit c51a7cdde4e1cb9014be401136c3f07f220ef365.
