[PATCH v4 13/15] pinctrl: qcom: add infrastructure for marking pin functions as GPIOs

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

Add a helper macro that wraps PINCTRL_GPIO_PINFUNCTION() for pinctrl-msm
pin functions and assign the .function_is_gpio() callback in pinmux_ops.
