media: dev-effect.rst: remove unused Effect Interface chapter 



We never had an effect interface, and if you want to do such
things you use the mem2mem interface instead.

Just drop this from the spec.

Effect Devices Interface

************************



.. note::

    This interface has been be suspended from the V4L2 API.

    The implementation for such effects should be done

    via mem2mem devices.



A V4L2 video effect device can do image effects, filtering, or combine

two or more images or image streams. For example video transitions or

wipes. Applications send data to be processed and receive the result

data either with :ref:`read() <func-read>` and

:ref:`write() <func-write>` functions, or through the streaming I/O

mechanism.
