[PATCH v2 2/2] uvcvideo: Add support for Intel SR300 depth camera

[evgeni.raikhel@gmail.com]

From: Daniel Patrick Johnson <teknotus@teknot.us>

Add support for Intel SR300 depth camera in uvc driver.
This includes adding three uvc GUIDs for the required pixel formats,
adding a new V4L pixel format definition to user api headers,
and updating the uvc driver GUID-to-4cc tables with the new formats.
