drivers: pinctrl: Add support for cc23x0 pinctrl 



Add support for pinctrl to cc23x0 SoC. Like for other TI SoCs,
a node approach is implemented (no grouping approach).

    TI SimpleLink CC23X0 pinctrl node.



    Device pin configuration should be placed in the child nodes of this node.

    Populate the 'pinmux' field with a pair consisting of a pin number and its IO

    functions.



    The node has the 'pinctrl' node label set in your SoC's devicetree,

    so you can modify it like this:



      &pinctrl {

              /* your modifications go here */

      };



    All device pin configurations should be placed in child nodes of the

    'pinctrl' node, as in the i2c0 example shown at the end.



    Here is a list of

    supported standard pin properties:



    - bias-disable: Disable pull-up/down.

    - bias-pull-down: Enable pull-down resistor.

    - bias-pull-up: Enable pull-up resistor.

    - drive-open-drain: Output driver is open-drain.

    - drive-open-source: Output driver is open-source.

    - input-enable: enable input.

    - input-schmitt-enable: enable input schmitt circuit.
