soc_camera_platform: remove obsolete soc_camera test driverbr-rmsensors2
This is a test stub driver for soc_camera. Since soc_camera is being deprecated (and in fact, nobody is using it anymore) there's no sense in keeping this test driver. Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

SoC Camera is a common API to several cameras, not connecting
over a bus like PCI or USB. For example some i2c camera connected
directly to the data bus of an SoC.
