[PATCH v4,1/5] dt-bindings: mt8173-xhci: support host side of dual-role mode

Some resources, such as IPPC register etc, shared with device driver are moved into common glue layer when xHCI driver is the host side of dual-role mode and they should be changed as optional properties if they are required ones before. For clarity, add a new part of binding to support host side
