    mediatek: filogic: increase flash speed on Netcore N60 Pro
    
    This commit increases the SPI bus frequency from 20 to 52 MHz. Reduces boot
    time by 2s. Below is a performance comparison.
    
    spi-max-frequency = <20000000>
    > time dd if=/dev/mtd4 of=/dev/null bs=10M count=1
    > 1+0 records in
    > 1+0 records out
    > real    0m 1.86s
    > user    0m 0.00s
    > sys     0m 0.28s
    
    spi-max-frequency = <52000000>
    > time dd if=/dev/mtd4 of=/dev/null bs=10M count=1
    > 1+0 records in
    > 1+0 records out
    > real    0m 1.04s
