Anson Huang f9a8744dde pinctrl: imx: Add imx8dxl driver 
i.MX8DXL contains a system controller that is responsible for controlling
the pad setting of the IPs that are present. Communication between the
host processor running an OS and the system controller happens through
a SCU protocol, add support for the SCU based i.MX8DXL pinctrl driver.
