[media] Staging: dt3155v4l: update to newer API

I changed the function definitions for dt3155_queue_setup() to match the
newer API.  The dt3155_start_streaming() function didn't do anything so
I just removed it.

This silences the following gcc warnings:
drivers/staging/media/dt3155v4l/dt3155v4l.c:307:2: warning: initialization from incompatible pointer type [enabled by default]
drivers/staging/media/dt3155v4l/dt3155v4l.c:307:2: warning: (near initialization for ‘q_ops.queue_setup’) [enabled by default]
drivers/staging/media/dt3155v4l/dt3155v4l.c:311:2: warning: initialization from incompatible pointer type [enabled by default]
drivers/staging/media/dt3155v4l/dt3155v4l.c:311:2: warning: (near initialization for ‘q_ops.start_streaming’) [enabled by default]
