ASoC: amd: renoir: Add a module parameter to influence pdm_gain
In case of regressions for any users that the new pdm_gain value is too high and for additional debugging, introduce a module parameter that would let them configure it.
This parameter should be removed in the future: * If it's determined that the parameter is not needed, just hardcode the correct value as before * If users do end up using it to debug and report different values we should introduce a config knob that can have policy set by ucm.

ASoC: AMD Renoir - add DMI entry for Lenovo ThinkPad X395
The ThinkPad X395 latop does not have the internal digital microphone connected to the AMD's ACP bridge, but it's advertised via BIOS. The internal microphone is connected to the HDA codec.
Use DMI to block the microphone PCM device for this platform.

ASoC: AMD Renoir - add DMI table to avoid the ACP mic probe (broken BIOS)
Users reported that some Lenovo AMD platforms do not have ACP microphone, 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 understandable way.

ASoC: AMD Raven/Renoir - fix the PCI probe (PCI revision)
The Raven and Renoir ACP can be distinguished by the PCI revision. Let's do the check very early, otherwise the wrong probe code can be run.
