pinctrl: qcom: ipq4019: mark gpio 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.
ipq4019 still describes its gpio function with QCA_PIN_FUNCTION(gpio),
so it is not treated as a GPIO pin function. As a result, GPIO consumers
can still conflict with pinctrl states that select the "gpio" function.
Add a QCA_GPIO_PIN_FUNCTION() helper and use it for the ipq4019 gpio
function, matching how the msm-based qcom drivers handle this.
This allows ipq4019 to keep the GPIO-related pin configuration in DTS
without tripping over strict pinmux ownership checks.
Fixes: cc85cb96e2e4 ("pinctrl: qcom: make the pinmuxing strict")
