pinctrl: add ZTE ZX pinctrl driver support The pin controller on ZTE ZX platforms is kinda of hybrid. It consists of a main controller and an auxiliary one. For example, on ZX296718 SoC, the main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both controllers work together to control pin multiplexing and configuration. For most of pins, the pinmux function is controlled by main controller only, and this type of pins are meant by term 'TOP pins'. For other pins, the pinmux is controlled by both main and auxiliary controllers, as the available multiplexing functions for the pin spread in both controllers. This type of pins are called 'AON pins'. Though pinmux implementation is quite different, pinconf is same for both types of pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG on ZX296718. The patch adds the ZTE ZX core pinctrl driver to support this hybrid pin controller as well as ZX296718 SoC specific pin data.
