ASoC: wm8960: Add ACPI support
HID made of either Wolfson/CirrusLogic PCI ID + 8960 identifier
This helps enumerate the Waveshare WM8960 WM8960 Hi-Fi Sound
Card HAT on the Up2 platform.
The scripts at https://github.com/thesofproject/acpi-scripts
can be used to add the ACPI initrd overlay.
This commit is similar to the commit:
