V4L/DVB (8610): Add suspend/resume capabilities to soc_camera.
Add suspend/resume hooks to call soc operation specific suspend and resume functions. This ensures the camera chip has been previously resumed, as well as the camera bus. These hooks in camera chip drivers should save/restore chip context between suspend and resume time.
