pinctrl: qcom: ipq806x: mark pci reset as a GPIO pin function

The qcom pinctrl core supports marking functions that represent GPIO mode
via PINCTRL_GPIO_PINFUNCTION(), so that strict pinmuxing does not reject
GPIO requests for pins that are muxed to the GPIO function.

Mark PCIe reset as GPIO pin function

This allows ipq806x to keep the PCIe-reset related configuration in DTS
without tripping over strict pinmux ownership checks.
