The tsadc supports two reset methods: the cru and the otp_gpio. All
boards except veyron and the evb simply use the cru-method and reuse the
pin for something else. On the Firefly-RK3288 this is for example the
case with the headphone. To prevent pinctrl-conflicts with these don't
set the otp-gpio pinctrl by default but only in the boards using it.
