Add pinctrl driver for i.MX8. The pads configuration is controlled by SCU, so need to ask SCU to configure pads through scfw API. Add pinctrl-scu to invoke sc_pad_set to configure pads. Add a new flag IMX8_USE_SCU to differentiate i.MX8 from other platforms which could directly configure pads from Acore side. Add CONFIG_PINCTRL_IMX8 as the built gate.
