    ath79: mikrotik: drop unused files from ramdisk
    
    The ramdisk used by sysupgrade on MikroTik devices currently includes
    U-Boot fw_* files that are not necessary for performing a system upgrade
    on that platform.  The relevant lines were added to
    target/linux/ath79/mikrotik/base-files/lib/upgrade/platform.sh by commit
    a66eee6336 ("ath79: add mikrotik subtarget"), likely because they also
    existed in target/linux/ath79/nand/base-files/lib/upgrade/platform.sh,
    where the platform_do_upgrade_mikrotik_nand() function moved by commit
    a66eee6336 originally lived.  However, these lines were added to
    target/linux/ath79/nand/base-files/lib/upgrade/platform.sh by commit
    55e6c903ae ("ath79: GL-AR300M: provide NAND support; increase to 4 MB
    kernel"), which is not related to MikroTik devices in any way.
    
    Remove the code adding unused U-Boot fw_* files to the ramdisk used by
    sysupgrade on MikroTik devices.
