[Linux-kernel-mentees] [PATCH v3 3/3] cec-compliance: refactor tuner control tests

[c0d1n61at3 at gmail.com (Jiunn Chang)]

Tests refactored for new features added to cec-collower.

Analog tuner control tests combined into tuner_ctl_test():
  - give analog tuner status
  - select tuner analog service
  - analog tuner step features
