Merge patch series "cmd: hash: correct parameter count check"

Heinrich Schuchardt <heinrich.schuchardt@canonical.com> says:

Since commit 348ea878508d ("cmd: hash: fix param count check") the hash
command cannot be used without the optional variable name parameter if
CONFIG_HASH_VERIFY=y. 'hash sha1 $loadaddr $filesize' returns
CMD_RET_USAGE.

The minimum number of arguments is four no matter if verification is
enabled or not.

Fix the parameter check.

Provide a unit test.
