+SiRFprimaII's pinmux nodes act as a container for an abitrary number of subnodes.
+Each of these subnodes represents some desired configuration for a group of pins.

+Required subnode-properties:
+- sirf,pins : An array of strings. Each string contains the name of a group.
+- sirf,function: A string containing the name of the function to mux to the
