Call the function of audio configure kill chroma in signal. only b/w video.

Why you use caps to define video input and audio with avideo and/or
aradio as flags? Better is , I think,  we use a struct for edge
virtual input (Video type (s-vhs, composite, tuner), video input pin
(video port a, video port b or both), video mode gpio, audio type ,
audio input pin (adc 1, adc 2 or sif)). If we are called
vidioc_s_input or radio_g_input setting input number. In tm6000_std.c
we can use this input number and the input struct with the same number
and can use all setting from here to set it.
