  1. drivers: pinctrl: Add pinctrl driver interface 

    Add the interface for pinctrl drivers.

Adapt the pinmux driver interface to use the pinctrl pinmux interface
if CONFIG_PINCTRL is selected. The pinctrl pinmux interface is a
generic shim that directly calls the pinctrl driver.

Add generic pin number defines for GPIO ports to be used by GPIO
drivers that use the pinctrl driver as backend driver.

The pin controller device driver:
    - enumerates controllable pins,
    - multiplexes pins, and
    - configures pins.

The Zephyr pin controller follows the concepts of the Linux PINCTRL
(PIN CONTROL) subsystem. However the Zephyr pin controller does not
provide the full scope of the Linux PINCTRL subsystem. Also the PINCTRL
interface is specific to Zephyr and not compatible (but similar)to the
Linux PINCTRL interface.
