media: atomisp: Remove atomisp_video_init() parametrization

Now that we only have a single /dev/video# node it is no longer
necessary for atomisp_video_init() to be parametrized.

Remove its parameters and while at it also change the name
from the single /dev/video# node from "ATOMISP ISP PREVIEW output"
to "ATOMISP video output".
