Add devicetree binding schema for the SoC-glue logic implemented on Socionext Uniphier SoCs. This SoC-glue logic is a set of miscellaneous function registers handling signals for specific devices outside system components, and also has multiple functions such as I/O pinmux, usb-phy, debug, clock-mux for a specific SoC, and so on.
