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.
