We'd have file conflicts when new a-t-c ships them.. so I'd think that's the correct place to put them right from the start. and with that, I've reverted this from the l-f branches.

From: Chris Chiu <chris.chiu@canonical.com> BugLink: https://bugs.launchpad.net/bugs/1915117 [Impact] Skylake, Kabylake, Kabylake-refresh, Amberlake and some other platforms where audio is of SPT (PCH) type, HDA (with DSP capabilities) plus DMIC configuration is supported on these with skylake driver since kernel 5.8. However, no sound card can be detected w/o the topology binary file in /lib/firmware and corresponding ucm file. [Fix] The kernel config CONFIG_SND_SOC_INTEL_SKYLAKE_HDAUDIO_CODEC needa to be enabled for the snd_soc_skl driver to support HDA+DMIC configuration. And the topology binary file and UCM files need to be located in the correct path based on Intel's suggestion. https://gist.github.com/crojewsk/4e6382bfb0dbfaaf60513174211f29cb. [Test] On the Skylake/Kabylake platforms with either the PCI device 8086:9d70 and 8086:9d71, boot up the machine and check the existence of the sound card by either 'aplay -l' or 'pactl list' command. [Where problems could occur] Should be low risk, it only affects limited Intel Platforms with particular PCI device IDs + HDA plus DMIC configuration.
