boards.d: Reformat ESP partition filesystem for the BeaglePlay board
    
    The bootROM for some SoCs (e.g: AM625 used in the BeaglePlay board) aren't
    able to boot when the ESP partition vfat filesystem geometry doesn't match
    the expected sectors/track and head numbers.
    
    Because the Fedora images are generated using a loopback device, they have
    a 63 sectors/track, 16 heads geometry but for SD block devices this should
    be 32 sectors/track, 64 heads for the AM625 SoC bootROM to boot the board.
    
    To make sure that the ESP vfat filesystem will have the correct geometry,
    reformat the partition when flashing the Fedora image to the block device.
