Title:
  [SRU] Load ucm on Lenovo notebooks based on bios version

Status in alsa-lib package in Ubuntu:
  Invalid
Status in alsa-lib source package in Bionic:
  Confirmed
Status in alsa-lib source package in Focal:
  Invalid

Bug description:
  [Impact]
  On some lenovo notebooks, ucm files are not loaded and mic can't be used

  [Fix]
  UCM was loaded based on cardlongname, but that can't cover all configs of the 
same model. Lenovo suggested to load  ucm by the first 3 letters of 
/sys/devices/virtual/dmi/id/bios_version, so that all configs could use just 
one ucm.

  [Test Case]

  [Regression Potential]
