pinctrl: make pinctrl_register() return proper error code
Currently, pinctrl_register() just returns NULL on error, so the
callers can not know the exact reason of the failure.
Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
-ENOMEM on error of pinctrl_register(), although the error code
might be different from the real cause of the error.
This commit reworks pinctrl_register() to return the appropriate
error code and modifies all of the pinctrl drivers to use IS_ERR()
for the error checking and PTR_ERR() for getting the error code.
