ramips: reduce spi-max-frequency for ipTIME A8004T
Reduce spi-max-frequency for ipTIME A8004T and disable
m25p,fast-read option.
A8004T uses `en25qh128` for the MTD.
This flash memory would allow 80MHz, sometimes kernel received
wrong id value in initramfs installed router.
(kernel expected `1c 70 18 1c 70 18`, but one of cases, it
was `9c 70 18 1c 70 18`)
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.
