env: register erase command
this patch adds basic changes for adding a erase-subcommand to env
with this command the environment stored on non-volatile storage written
by saveenv can be cleared.
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
squashed fixes
- start message with "Erasing"
- mark erase-function as optional
- env: separate eraseenv from saveenv
