drm/tegra: dpaux: Fix error handling
The devm_pinctrl_register() function returns an error pointer or a valid handle. So checking for NULL here is pointless and can never trigger. Check the returned value with IS_ERR instead and propagate this value as done in the other functions which call devm_pinctrl_register().
