pinctrl: imx: use radix trees for groups and functions
This change is inspired from the pinctrl-single architecture.
The problem with current implementation is that it isn't possible
to add/remove functions and/or groups dynamically. The radix tree
offers an easy way to do so. The intent is to offer a follow-up
patch later that will enable the use of pinctrl nodes in dt-overlays.
