Title:
  ucm2: soundwire: add rt713 SDCA device

Status in alsa-ucm-conf package in Ubuntu:
  New

Bug description:
  [ Impact ]
  Affects devices with SoundWire-Audio Codec-ALC713 and SoundWire-Jack Codec-ALC713.
  Without correct configurations in userspace above codecs cannot be used. Thus in Settings > Sound > Output test doesn't produce sounds and Input device is greyed out.

  [ Fix ]
  Adding rt713 config files in ucm2 will allow to utilize those codecs.
  Upstream commit added support: https://github.com/alsa-project/alsa-ucm-conf/pull/363

  [ Test Plan ]
  Device with the soundwire card

  $ cat /proc/asound/cards
   0 [sofsoundwire   ]: sof-soundwire - sof-soundwire
                        Intel Soundwire SOF

  Before fix:

  1. $ alsactl init
  alsa-lib utils.c:364:(uc_mgr_config_load_into) could not open configuration file /usr/share/alsa/ucm2/sof-soundwire/rt713.conf
  alsa-lib parser.c:77:(uc_mgr_config_load_file) error: failed to open file /usr/share/alsa/ucm2/sof-soundwire/rt713.conf: -2
  alsa-lib main.c:1412:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -2
  Found hardware: "sof-soundwire" "Intel Meteorlake HDMI" "HDA:8086281d,80860101,00100000 cfg-spk:2 cfg-amp:2 hs:rt713-sdca spk:rt1316 mic:rt713-dmic" "" ""
  Hardware is initialized using a generic method

  2. $ amixer contents
  ...
  numid=24,iface=MIXER,name='Headphone Switch'
    ; type=BOOLEAN,access=rw------,values=1
    : values=off
  ...
  numid=33,iface=MIXER,name='IEC958 Playback Switch'
    ; type=BOOLEAN,access=rw------,values=1
    : values=off

  After fix: after adding patch files

  1. $ alsactl init
  alsa-lib main.c:779:(execute_sequence) exec '/bin/rm -rf /var/lib/alsa/card0.conf.d' failed (exit code 1)

  (note: assuming that failed to remove the empty directory is not a
  critical problem)

  2. $ amixer contents
  ...
  numid=24,iface=MIXER,name='Headphone Switch'
    ; type=BOOLEAN,access=rw------,values=1
    : values=on
  ...
  numid=33,iface=MIXER,name='IEC958 Playback Switch'
    ; type=BOOLEAN,access=rw------,values=1
    : values=on

  [Where problems could occur]

   * This change adds new hardware support.

   * The change only adds new hardware support,
     it will not affect other codec device.
