The SoundWire-related information provided by platform firmware (DSDT)
hasn't changed since 2016, but with a recent change of device
hierarchy we need to change how the controller is detected.
These patches were tested on existing devices and don't break
anything, but are very much needed for newer devices (quirks already
in Linus' branch for 5.16, see e.g. commit f55af7055cd4 ("ASoC: Intel:
sof_sdw: Add support for SKU 0B12 product"). Unfortunately the BIOS
changes happened *after* the initial patches were contributed.

ALSA: hda: intel-sdw-acpi: go through HDAS ACPI at max depth of 2
