npcx: Define CONFIG_DATA_RAM_SIZE
This patch defines CONFIG_DATA_RAM_SIZE, which indicates the size
of the RAM used for data, thus can be marked as non-executable.
If it's not defined, it defaults to CONFIG_RAM_SIZE. Thus, other chips
are not affected.
BUG=b:36037354
BRANCH=none
TEST=buildall. Run 'sysjump disable' on Reef and verify mpu_protect_ram
is successful.
