    ramips: dts: increase maximum MMC clock frequency
    
    The High-Speed SD mode stability issue should have been fixed.
    Increase the MMC max-frequency to improve the IO speed. We can
    still use the sysfs to limit the clock frequency, e.g.
    
    root at OpenWrt:~# echo 25000000 > /sys/kernel/debug/mmc0/clock
