media: atomisp: Remove depth-mode support

Remove support for depth mode. This is a special mode where 2 streams
(from 2 different sensors) can be setup and then starting/stopping
1 will automatically also start/stop the other.

Like many of these special features I'm pretty sure that if the queue
setup is not done exactly right things will crash and there is no error
checking for this.

This seems to be for stereoscopic vision and the only known hw which
actually supports this is the Intel Aero board/SDK, all other 1000+
BYT/CHT models don't need this.

This false outside of the standard webcam use scenario which we are
trying to get working and this involves a bunch of hacks / special
exceptions all over the code, so lets remove this.
