V4L/DVB (8040): soc-camera: remove soc_camera_host_class class
Devices can either be class devices or bus devices, not both at the same time. Soc-camera host devices usually have a platform device as their parent. Trying to also register them with a class crashes the kernel, when linked statically. Interestingly, it works when built as a module. Thanks to Paulius Zaleckas for reporting.
