[PATCH] Generic HID layer - USB API

Browse source 
- 'dev' in struct hid_device changed from struct usb_device to
  struct device and fixed all the users
- renamed functions which are part of USB HID API from 'hid_*' to
  'usbhid_*'
- force feedback initialization moved from common part into USB-specific
  driver
- added usbhid.h header for USB HID API users
- removed USB-specific fields from struct hid_device and moved them
  to new usbhid_device, which is pointed to by hid_device->driver_data
- fixed all USB users to use this new structure
