usb: dwc3: eic7700: Add EIC7700 USB driver

The EIC7700 instantiates two USB 3.0 DWC3 IPs, each of which is backward
compatible with USB interfaces. It supports Super-speed (5Gb/s), DRD mode,
and compatible with xHCI 1.1, etc. Each of instances supports 16 endpoints
in device's mode and max 64 devices in host's mode.

This module needs to interact with the NOC via the AXI master bus, thus
requiring some HSP configuration operations to achieve this. Ops include
bus filter, pm signal or status to usb bus and so on.
