ASoC: hdac_hdmi: Move channel info from pin to PCM structure
Channel info is part of the pcm parameter and channel map control is created for each pcm. So move channel info to pcm instead of pin structure and the mutex lock to pcm. Signed-off-by: Jeeja KP <jeeja.kp@intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>hifive-unleashed-5.1
