This is actually more or less a revert of a previous commit:
b28742be4709 pinctrl: imx: remove const qualifier of imx_pinctrl_soc_info

Note that the idea for this commit was to get dt-overlays working and
able to do pinctrl changes using configfs interface to load an overlay
(using Pantelis patch). Not sure where we stand on loading such overlay
from user-space, is it still something that will happen?
