    ramips: fix Mercury MAC1200R v2.0 board name
    
    With d2b6bf141662 ("ramips: fix image validation errors") the board
    name was changed to fix an image validation error. But this change
    wasn't applied to all other files using the board name, which broke
    sysupgrade.
    
    Revert this change and use the former board name in the metadata
    instead.
