[PATCH v4 1/6] usb: uvc: include videodev2.h in g_uvc.h

[Paul Elder]

V4L2_EVENT_PRIVATE_START is used in g_uvc.h but is defined in
videodev2.h, which is not included and causes a compiler warning:

linux/usb/g_uvc.h:15:28: error: âV4L2_EVENT_PRIVATE_STARTâ undeclared here (not in a function)
 #define UVC_EVENT_FIRST   (V4L2_EVENT_PRIVATE_START + 0)

Include videodev2.h in g_uvc.h.
