The GXP hub controller presents a four ports to host software.
Each port is logically connected to one control endpoint and
four generic endpoints.

---

Changes since v1:
 *Renamed binding.
 *Removed all unneeded include files.
 *Using generic node name, usb-hub.
 *Removed of_match_ptr().
 *Using helper for both get resource and IO remap.
 *Using dev_err_probe() return in probe routine.
 *Used sizeof(*...) in the code instead of sizeof(struct...).
 *Removed the term "virtual" as it is still a device.
 *Removed the downstream port number and generic endpoints
  number properties from device tree structure.
