[PATCH v2 2/2] env: remote: Disallow CMD_SAVEENV

[Tom Rini <trini@konsulko.com>]

Looking at how the saveenv portion of this driver was implemented, it
does not appear that it could actually result in changes being saved on
the remote end. Update Kconfig to disallow CMD_SAVEENV for
ENV_IS_IN_REMOTE and then remove the relevant code.
