4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@arndb.de>

commit ff681022c6639c194fbb6893c50ace9e52a44788 upstream.

Moving the pxa_camera driver from soc_camera lots the implied
VIDEO_V4L2 Kconfig dependency, and building the driver without
V4L2 results in a kernel that cannot link:

drivers/media/platform/pxa_camera.o: In function `pxa_camera_remove':
pxa_camera.c:(.text.pxa_camera_remove+0x10): undefined reference to `v4l2_clk_unregister'
pxa_camera.c:(.text.pxa_camera_remove+0x18): undefined reference to `v4l2_device_unregister'
drivers/media/platform/pxa_camera.o: In function `pxa_camera_probe':
pxa_camera.c:(.text.pxa_camera_probe+0x458): undefined reference to `v4l2_of_parse_endpoint'
drivers/media/v4l2-core/videobuf2-core.o: In function `__enqueue_in_driver':
drivers/media/v4l2-core/videobuf2-core.o: In function `vb2_core_streamon':
videobuf2-core.c:(.text.vb2_core_streamon+0x1b4): undefined reference to `v4l_vb2q_enable_media_source'
drivers/media/v4l2-core/videobuf2-v4l2.o: In function `vb2_ioctl_reqbufs':
videobuf2-v4l2.c:(.text.vb2_ioctl_reqbufs+0xc): undefined reference to `video_devdata'

This adds back an explicit dependency.
