 hmm, as mentioned in the previous patch, feels better to enable
 it only in the board file specifically and not to touch this here
 and the common dtsi.

 hmm, the additional pins were required for zigbee connected as the
 spidev device. So the right probably is to have the additional
 pins required for the device populated under the spi's child node.

 ok, let me check.
