If device provide the max frequency then the spi communciation will on 
this requested frequency.
If device does not provide the max spi frequency then it will 
communciate with the controller max frequency.

In this case we provide the 20MHz for device and 25MHz for controller. 
So spi communciation with this device will be always 20MHz.
