Kconfig: Finish migration of hashing commands

Currently these (board agnostic) commands cannot be selected using
menuconfig and friends. Fix this the obvious way.  As part of this,
don't muddle the meaning of CONFIG_HASH_VERIFY to mean both 'hash -v'
and "we have a hashing command" as this makes the Kconfig logic odd.

        migrate CRC32_VERIFY]
