[Fix] Backport 3 patches from upstream. [Test Case] On the 3 Lenovo ADM renoir machines, boot the kernel with this patchset, all dmic could be detected and registered as before. Disable the dmic in the BIOS, the driver can't detect the dmic and the dmic is not registered in the driver. [Regression Risk] Low, this SRU are only specific to soc/amd/renoir, and we already tested on 3 lenovo machines, they worked as expected.
