Subject: [PATCH] [media] pxa_camera: add V4L2 dependency

Moving this driver out of soc_camera has resulted in a new randconfig failure:

drivers/media/built-in.o: In function `pxa_camera_remove':
pxa_camera.c:(.text+0x1854d): undefined reference to `v4l2_clk_unregister'
pxa_camera.c:(.text+0x18555): undefined reference to `v4l2_device_unregister'
drivers/media/built-in.o: In function `pxa_camera_sensor_unbind':
pxa_camera.c:(.text+0x185dd): undefined reference to `video_unregister_device'

As the driver now can be built for COMPILE_TEST as well, this means we
can see the problem even on non-PXA platforms.
Adding a dependency on VIDEO_V4L2 ensures this cannot happen and matches
what the other drivers do.

Fixes: 4bb738f228b3 ("[media] media: platform: pxa_camera: move pxa_camera out of soc_camera")
Fixes: 5809ecdd6c3c ("[media] pxa_camera: allow building it if COMPILE_TEST is set")
