Devendra Naga 0bf7481852 pinctrl: pinctrl-mxs: Take care of frees if the kzalloc fails
if there is no purecfg , the group pointer is allocated using kzalloc and if it
fails to allocate, we wont free the new_map,

if config is true, we call kmemdup and if it
fails to do so we wont free the allocated group if there is no purecfg.

fix this by doing the frees of new_map pointer and group pointers.

Shawn Guo 4851680491 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.
