media: soc_camera_platform: remove obsolete soc_camera test driver
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.

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.

This is a generic SoC camera platform driver, useful for testing
