dt-bindings: soc: socionext: Add UniPhier SoC-glue logic debug part

Add devicetree binding schema for the SoC-glue logic debug part
implemented on Socionext Uniphier SoCs.

This SoC-glue logic debug part is a set of miscellaneous function
registers handling signals for specific devices outside system
components, and also has multiple functions such as efuse, debug unit,
several monitors for specific SoC, and so on.
