media: soc_camera: Remove the rj45n1 SoC camera sensor driver
There is a V4L2 sub-device sensor driver for the rj45n1. As there is already another driver, remove the SoC camera one. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Acked-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
