pinctrl: qcom: msm8916: Allow CAMSS GP clocks to be muxed

commit 44339391c666e46cba522d19c65a6ad1071c68b7 upstream.

GPIO 31, 32 can be muxed to GCC_CAMSS_GP(1,2)_CLK respectively but the
function was never assigned to the pingroup (even though the function
exists already).

Add this mode to the related pins.
