ramips: reduce spi-max-frequency for ipTIME A8004T

Browse Source 
Reduce spi-max-frequency for ipTIME A8004T and disable
m25p,fast-read option.

In this case, openwrt can't detect the partition information,
it would write the inccorect data to the firmware partition and
also it would occur the bootlooping after sysupgrade.
