[Frank Wunderlich]

sometimes it is needed to erase the non-volatile environment
e.g. for boot-up with builtin-environment or after resizing env

this series add basic functionality for erasing environment from
storage as a first storage-driver mmc is introduced, other needs to be added
later

changes since v4:
 - rebased to 2019.07-rc4
 - changed handling with CONFIG_ENV_OFFSET_REDUND (more similar to saveenv)
 - quashed last 2 commits to get 2-parts patchset

Frank Wunderlich (2):
  env: register erase command
  env: mmc: add erase-function
