media: ov6650: Fix missing frame interval enumeration support
According to v4l2-compliance utility, a video device which supports
V4L2_CAP_TIMEPERFRAME via .vidioc_s_parm() operation should also
support .vidioc_enum_frameintervals(). If the former is implemented
via a call to v4l2_s_parm_cap() which in turn calls a subdevice
.s_frame_interval() pad operation, the video device may want to
implement the latter by passing frame interval enumeration requests to
the subdevice .enum_frame_intervals() video operation. If that
operation is not supported by the subdevice and failure is returned by
the video device, the compliance test issues a warning.
Implement the missing pad operation. Enumerate frame intervals
possible to be set via pixel clock adjustment, as implemented by
.s_frame_interval(), but not exceeding a reasonable maximum of 1
second.
