ARM: S3C24XX: Add plaform device definition for USB High-Speed gadget controller. 



S3C2416, S3C2443 and S3C2450 includes a USB High-Speed Gadget controller module.
This patch adds the following for supporting this controller.

1. Definition for USB High-Speed controller base address.
2. Platform device instantiation.
3. Declaration for platform data structure.
4. Functionality to setup platform data for the controller.
