Bug description:
This patchset is for mainline kernel-5.8, after backporting to 5.6,
there is no need to change anything, but after backporting to 5.4
kernel, because of API differences, need to do some change to adapt
to 5.4 kernel's API. So there is one more patch for focal than for
oem-5.6.

[Impact]
We have a couple of LENOVO machines which has amd renoir audio on
them, our kernel doesn't have the driver for it yet.

[Fix]
amd just upstreamed the driver, it is for kernel-5.8, we backport
them to ubunt kernel.

[Test Case]
boot the kernel with those patches, we could see a sound card named
"acp" and the dmic on it could record sound via arecord.

[Regression Risk]
Low, just adding a new driver, no change to existing drivers.
