7.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans Ulli Kroll <[email protected]>

[ Upstream commit 687f39faccba29ab26de965411db37e849af8ec2 ]

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: cc85cb96e2e4 ("pinctrl: qcom: make the pinmuxing strict")
