ARM: dts: kirkwood: set default pinctrl for SPI0
Most Kirkwood boards use the default SPI0 pinctrl setting anyway. Add a default pinctrl setting to the toplevel SoC SPI0 node and put a note in front of the corresponding pinctrl node to overwrite the setting on board level. Currently, only T5325 is using a different setting and already overwrites the corresponding pinctrl node.
