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.
Let's define a way to configure these pins as gpio or pwm.
Also add gpio-range property in the dts example.
