V4L/DVB (6293): V4L: convert struct class_device to struct device

to struct device.

This next batch of horrible preprocessor hackery is needed because the
kernel's class_device_attribute mechanism fails to pass the actual
kernel's device_attribute mechanism fails to pass the actual
attribute through to the show / store functions, which means we have no
way to package up any attribute-specific parameters, like for example the
control id. So we work around this brain-damage by encoding the control
