V4L/DVB (6881): include struct analog_demod_ops directly inside struc…

…t dvb_frontend Rather than using a pointer, include struct analog_demod_ops directly inside struct dvb_frontend. This will allow us to use dvb_attach in the future, along with removing the need to check the ops structure before having to check the pointer to the method being called.
