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.
