pinctrl: msm: Actually use function 0 for gpio selection

This code needs to select function #0, which is the first int in the
array of functions, not the number 0 which may or may not be the
function for "GPIO mode" per the enum mapping. We were getting lucky on
SDM845, where this was tested, because the function 0 matched the enum
value for "GPIO mode". On other platforms, e.g. MSM8996, the gpio enum
value is the last one in the list so this code doesn't work and we see a
warning at boot. Fix it by grabbing the first element out of the array
of functions.
