pinctrl: Add pinctrl driver for i.MX8
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.
