Michael Lyle 961e01fc67 ramips: gl-mt1300: downclock SPI to 50MHz ...

The SPI max frequency was set to 80MHz, considerably higher than the
vendor clocks it in their firmware (10MHz).  Multiple users reported
jffs2 corruption/instability in GitHub issue #10461.

My unit has a W25Q256; datasheet specifies maximum SPI frequency for
read command of 50MHz.

Thanks to @DragonBlueP for suggesting to eliminate m25p,fast-read;
and @MPannen1979 for identifying the problem.

Fixes: #10461
