pinctrl: rockchip: add function node valid check

Browse Source 
There are many kinds of nodes under pinctrl node, such as function
nodes, gpio nodes, and pcfg nodes.

The driver do a match check for the nodes, to ignore the gpio nodes.
This patch try to put the valid check as a function, it's better to
avoid error fix.
