[SRU][linux-firmware][Focal/Groovy][PATCH 0/1] sof-firmware: support 1 and 3 dmics

[Hui Wang]

BugLink: https://bugs.launchpad.net/bugs/1891585

[Impact]
On a Dell tigerlake laptop, the sof driver fails to detect the dmic,
it alwasys report 0 dmics on the machine. So users doesn't have
internal mic to use.

[Fix]
Intel provides 2 new topology files to us, they could support 1
dmic and 3 dmics.

[Test Case]
Boot the kernel with this patch, and put sof-hda-generic-1ch.tplg in
the linux-firmware, the sof driver could detect the dmic and users
have a workable internal mic after booting up.

[Regression Risk]
This is adding 2 new topology files, not changing anything on
current sof-firmware, so the regression posibility is very low.
