Subject: [PATCH] configs: SiFive Unmatched: enable 'env erase' sub-command

With the move from script based booting to using bootmeth a lot of
environment variables have changed. To always use the default environment
it is recommendable to erase the environment stored in the SPI flash.
This can be done with the 'env erase' sub-command.
