[PATCH] TDA9887 PAL-Nc fix

[Gonzalo de la Vega <gadelavega@gmail.com>]

The tunner IF for PAL-Nc norm, which AFAIK is used only in Argentina, was being defined as equal to PAL-M but it is not. It actually uses the same video IF as PAL-BG (and unlike PAL-M) but the audio is at 4.5MHz (same as PAL-M). A separate structure member was added for PAL-Nc.
