pinctrl: mxs: skip gpio nodes for group creation
The recent added mxs gpio device tree bindings require gpio nodes defined under pinctrl node too. The pinctrl-mxs driver should skip these node for group parsing and creating. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
