stable inclusion from stable-5.10.67 commit a64e3f1d8a27f6868e01f99f7f21519e46da61fb bugzilla: 182619 https://gitee.com/openeuler/kernel/issues/I4EWO7
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit 22414cade8dfec25ab94df52b3a4f7aa8edb6120 ]
The default SOF topology enables SSP capture and DMICs, even though both of these hardware capabilities are not always available in hardware (specific versions of HiFiberry and DMIC kit needed).
For the SSP capture, this leads to annoying "SP5-Codec: ASoC: no backend capture" and "streamSSP5-Codec: ASoC: no users capture at close - state 0" errors.
Update the quirks to match what the topology needs, which also allows for the ability to remove SSP capture and DMIC support.
