PCM buffers might be allocated dynamically when the buffer
preallocation failed or a larger buffer is requested, and it's not
guaranteed that substream->dma_buffer points to the actually used
buffer. The driver needs to refer to substream->runtime->dma_addr
instead for the buffer address.

but the BIOS advertises it via ACPI.
This patch create a simple DMI table, where those machines with the broken
BIOS can be added. The DMI description for Lenovo IdeaPad 5 and
IdeaPad Flex 5 devices are added there.
Also describe the dmic_acpi_check kernel module parameter in a more

AMD Renoir driver tries to identify the presence of DMIC by evaluating
ACPI _WOV entry, and it returns -EINVAL when the ACPI call failed.
This ended up an error message like
snd_rn_pci_acp3x: probe of 0000:04:00.5 failed with error -22
although the system is correctly set up.
For avoiding such a superfluous error message, change the return value
to -ENODEV. Then the driver core just skips to the next one without
complaining.

Recently we found an issue about the suspend and resume. If dmic is
recording the sound, and we run suspend and resume, after the resume,
the dmic can't work well anymore. we need to close the app and reopen
the app, then the dmic could record the sound again.
For example, we run "arecord -D hw:CARD=acp,DEV=0 -f S32_LE -c 2
-r 48000 test.wav", then suspend and resume, after the system resume
back, we speak to the dmic. then stop the arecord, use aplay to play
the test.wav, we could hear the sound recorded after resume is weird,
it is not what we speak to the dmic.
I found two registers are set in the dai_hw_params(), if the two
registers are set during the resume, this issue could be fixed.
Move the code of the dai_hw_params() into the pdm_dai_trigger(), then
these two registers will be set during resume since pdm_dai_trigger()
will be called during resume. And delete the empty function
dai_hw_params().
