[PATCH] Generic HID layer - hiddev

- hiddev is USB-only (agreed with Marcel Holtmann that Bluetooth currently
  doesn't need it, and future planned interface (rawhid) will be more flexible
  and usable)
- both HID and USB-hid can be now compiled as modules (wasn't possible before
  hiddev was fully separated from generic HID layer)
