[PATCH v9 07/36] dt-bindings: pinctrl: airoha: en7581: allow configuration of pcie_reset pins as gpio or pwm

In the an7581 case
 * gpio47 and pcie_reset0 shares the same pin,
 * gpio48 and pcie_reset1 shares the same pin,
 * gpio49 and pcie_reset2 shares the same pin.

This patch defines a way to configure these pins as gpio or pwm.
