cec-follower: rename freq_idx to service_idx
The implementation of digital support in tuner control requires the renaming of freq_idx to service_idx as analog and digital channels are referred to collectively as services. The index will now represent the current state of both analog and digital. Tuner step features will cycle through both analog and digital with digital preceeding analog.
