ramips: reduce Archer AX23 / MR70X SPI-frequency 

It was brought to attention the Archer AX23 v1 fails to read jffs2 data
from time to time. While this is not reproducible on my unit, it is on
others.

Reducing the SPI frequency does the trick. While it worked with at lest
40 MHz, opt for the cautious side and choose a save frequency of 25 MHz.

Apply the same treatment to the Mercusys MR70X which uses a similar
design just in case.
