Bug description:
  [Impact]
  On the LENOVO AMD Renoir machines, there is a digital mic directly
  connected to the APU instead of the codec, so there are two separate
  sound cards in the system, one is for analogue codec driven by hda
  driver, the other is for the dmic driven by ASoC acp driver.

  The current audio stack (pulseaudio + alsa-ucm-conf + alsa-lib) doesn't
  support this design yet, it could support all audio devices on the codec
  well, but it doesn't support that dmic well. In the gnome-control-center,
  the dmic becomes two input devices: analog input and multichannel input,
  and users can only record sound from analog input, the multichannel input
  can't function at all. Besides this issue, there is another issue, after
  users plug an external mic, the external mic can't replace the dmic
  automatically, this gives users a bad experience since this behaviour is
  different from the other audio designs.

  add Breaks alsa-ucm-conf (<= 1.2.2-1ubuntu0.1) in the d/control
  add snd_config_is_array@ALSA_0.9 1.2.2-2.1ubuntu1 in the d/libasound2.symbols

  [Test Case]
  On the AMD Renoir machines:
  * Boot the system with these updated packages (already backported kernel
  drivers to Focal and oem-5.6 kernels), open the gnome-control-center
   - we could see the digital mic in the input device tab, and only one
  input device
   - we could record sound through this dmic
   - we could play sound through the speaker
   - plug a headset, we could see the output device become headphones and the 
input device become headset mic
     - we could play sound to headphone and record sound from headset mic
   - plug an HDMI monitor, there is HDMI audio choice
     - play sound to HDMI audio, we could hear the sound from the speaker on 
the monitor
   - Suspend and resume, redo the previous steps, all audio devices still work 
well.

  On other machines:
  Boot the system with all updated packages or partial updated packages,
  check all input devices and output devices, they worked the same as
  before. this SRU doesn't bring any impact on other machines.

  [Regression Risk]
  Low
  For alsa-ucm-conf, this SRU adds two new folders and only minimum
  changes on existing folders, and these changes are under control and
  are for supporting acp driver.
  For alsa-lib, this SRU only adds the patches to support the ucm 3, and
  nearly all changes are in the ucm folder. there is no external ABI or
  API changes
  For pulseaudio, this SRU only integrate 3 patches, and 2 of them are
  for auto switching, and they are small patches and already upstreamed.
  the left patch are specific to Renoir audio, it will not bring impact
  to other machines.

  Also, we tested these changes with below machines:
  A LENOVO AMD Renoir laptop, all audio function works and no regression
  found
  A DELL laptop with intel dmic, all audio function works and no
  regression found
  A DELL laptop with intel soundwire audio, all audio function works and
  no regression found
