This frequency table will allow proper testing of tuner control. There
are three frequencies per analog broadcast type and broadcast system, so
tuner increment and decrement can be tested.

Changes since v1:
- Add Wikipedia link for analog channel frequencies
- Add spaces between { and }
Changes since v2:
- Refactor lines numbers since a fix patch was needed for cec-tuner.cpp
