util/ifdtool: Add lock support for CNL and ICL

Cannonlake and Icelake have same read/write region permission settings
with skylake and kabylake, so add it here as well.

BUG=b:123199222
TEST=Turn on CONFIG_LOCK_MANAGEMENT_ENGINE and build image, check the
setting matches 0x0D for read and 0x04 for write.
