cmd: mmc: Expand bkops handling

Browse Source 
Add more capable "bkops" command which allows enabling and disabling both
manual and automatic bkops. The existing 'mmc bkops-enable' subcommand is
poorly named to cover all the possibilities, hence the new-ish subcommand.
Note that both commands are wrappers around the same common code.
