dt-bindings: pinctrl: nrf: allow for more ports

 * The whole nRF pin configuration information is encoded in a 32-bit bitfield

 * organized as follows:

 *

 * - 31..16: Pin function.

 * - 15:     Reserved.

 * - 14:     Pin inversion mode.

 * - 13:     Pin low power mode.

 * - 12..9:  Pin output drive configuration.

 * - 8..7:   Pin pull configuration.

 * - 6..0:   Pin number (combination of port and pin).

 * - 31..17: Pin function.

 * - 16:     Pin inversion mode.

 * - 15:     Pin low power mode.

 * - 14..11: Pin output drive configuration.

 * - 10..9:  Pin pull configuration.

 * - 8..0:   Pin number (combination of port and pin).
