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 made since v1:
- Add Wikipedia link for analog channel frequencies
- Add spaces between { and }
Changes made since v2:
- Add reply_feature_abort() to cec-tuner.cpp
- Refactor lines numbers since a fix patch was needed for cec-tuner.cpp
Changes made since v3:
- Remove reply_feature_abort() from cec-tuner.cpp
- Add macro for NUM_ANALOG_FREQS
- Refactor lines numbers since a fix patch was needed for cec-tuner.cpp
