Move cec_get/put_device to the media/cec.h header. This
allows CEC drivers to use this.

Explicitly disable the CEC adapter in cec_devnode_unregister()
Usually this does not really do anything important, but for drivers
that use the CEC pin framework this is needed to properly stop the
hrtimer. Without this a crash would happen when such a driver is
unloaded with rmmod.

Use call_(void_)op consistently in the CEC core framework. Ditto
for the cec pin ops. And check if !adap->devnode.unregistered before
calling each op. This avoids calls to ops when the device has been
unregistered and the underlying hardware may be gone.

In preparation for moving CEC drivers to the CEC directory,
move the core to a separate place.
