pinctrl: Add devm_ apis for pinctrl_{register, unregister}

Browse Source 
Add device managed APIs devm_pinctrl_register() and
devm_pinctrl_unregister() for the APIs pinctrl_register()
and pinctrl_unregister().

This helps in reducing code in error path and sometimes
removal of .remove callback for driver unbind.
