[media] fc0012: remove unused callback and correct one comment
There is no need to keep dummy sleep() callback implementation as DVB-core checks existence of it before calls callback. Due to that we can remove it. FC0012 is based of direct-conversion receiver architecture (aka Zero-IF) where is no IF used. Due to that IF is always 0 Hz. Fix comment to point that.
