soc/amd/common/acpi: Add _UID for PNP0C02 devices 

When MAINBOARD_HAS_SPEAKER is false, the SPKR gets _HID PNP0C02. This
conflicts with the LDRC device. PNP0C02 is also used other places in the
picasso code base, so I chose a random _UID for each device. The _UIDs
are unique in the code base so it's easy to search for duplicates.
