ASoC: wm8804: Add ACPI support
[ Upstream commit 960cdd50ca9fdfeb82c2757107bcb7f93c8d7d41 ] HID made of either Wolfson/CirrusLogic PCI ID + 8804 identifier. This helps enumerate the HifiBerry Digi+ HAT boards on the Up2 platform. The scripts at https://github.com/thesofproject/acpi-scripts can be used to add the ACPI initrd overlays.
