USB device driver of Topcliff PCH
This patch adds the USB device driver of EG20T(Topcliff) PCH. EG20T PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platform. All IO peripherals in EG20T PCH are actually devices sitting on AMBA bus. EG20T PCH has USB device I/F. Using this I/F, it is able to access system devices connected to USB device.
