media: atomisp: Remove const/fixed camera_caps

The code checks a camera_caps struct in various places, but this always
points to the same const camera_caps struct.

Remove the checks, keeping the code paths which would be taken with
the fixed camera caps struct still in place and remove the camera_caps
struct itself.

Note this completely removes atomisp_pause_buffer_event() because that
only ever does something if camera_caps.sensors[0].is_slave is true and
that never is true.
