media: atomisp: Register only 1 /dev/video# node

Now that we no longer support continuous mode and thus no longer support
streaming from 2 /dev/video# nodes at the same time, there is no need
to have a separate /dev/video# node (+ matching v4l2-subdev pads)
for each run-mode.

Keep the video_out_preview /dev/video0 device and remove
the video_out_video_capture / video_out_vf / video_out_capture
video-devices (atomisp_pipe-s) and also remove the matching
ATOMISP_SUBDEV_PAD_SOURCE_VIDEO / ATOMISP_SUBDEV_PAD_SOURCE_VF /
ATOMISP_SUBDEV_PAD_SOURCE_CAPTURE source-pads.
