ramips: gl-mt1300: downclock SPI to 50MHz

Browse Source 
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.

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