This patch series implements analog tuner step features and cec-compliance tests.
Added tuner_ctl_test() to test new tuner features implemented in the cec-follower.

---

Changes made since v4:
  - Add TOT_ANALOG_FREQS macro: hverkuil
  - Rename function to analog_update_tuner_dev_info(): hverkuil
  - Set freq_idx in analog_update_tuner_dev_info(): hverkuil
  - Reuse info variable in tuner_ctl_test(): hverkuil
  - Refactor tuner_ctl_test() to leverage timed_out_or_abort() and
    abort_reason(): hverkuil

changes made since v3:
  - Correct commit message for tuner emulation bug fix
  - Refactor analog_get_nearest_freq_idx() to return freq index
  - Refactor analog_get_type_system_idx() to set device info
  - Add macro ARRAY_SIZE_ANA_FREQS
  - Refactor tuner_ctl_test() to use std::vector

Changes made since v2:
  - Fix bugs for tuner emulation
  - Add freq_idx to cec-follower state
  - Refactor tuner tests into a single tuner_ctl_test()

Changes made since v1:
  - Remove redundant error checking
  - Add circular wrap logic to tuner step increment/decrement
