be3ae00ff9 soundwire: Intel: add DMI quirk for Dell SKU 0A3E 
We've been handling ACPI issues on early versions of the product with
a local ACPI initrd override but now that we have the possibility of a
kernel quirk let's get rid of the initrd override. This helps make
sure that the kernel will support all versions of the BIOS, with or
without updates.

f6594cdfec soundwire: Intel: introduce DMI quirks for HP Spectre x360 Convertible 
HP Spectre x360 Convertible devices expose invalid _ADR fields in the
DSDT, which prevents codec drivers from probing. A possible solution
is to override the DSDT, but that's just too painful for users.

This patch suggests a simple DMI-based quirk to remap the existing
invalid ADR information into valid ones.
