Add DT binding schema for components belonging to the platform-specific
AHCI glue layer implemented in UniPhier SoCs.

This AHCI glue layer works as a sideband logic for the host controller,
including core reset, PHYs, and some signals to the controller.

What is the additional object? It's not in your example, not in DTS. Why
do you need to allow it?
