pinctrl: qcom: ipq806x: mark gpio as a GPIO pin function

Browse Source 
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.

Add a IPQ_GPIO_PIN_FUNCTION() helper and use it for the ipq806x gpio
function, matching how the msm-based qcom drivers handle this.

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

Fixes: cc85cb96e2 ("pinctrl: qcom: make the pinmuxing strict")
