soc/amd/stonyridge: Give I2C devices unique _UIDs
The ACPI unique identifier (_UID) should be unique.
This doesn't actually matter much for Linux, though, since the kernel
can handle it when the BIOS doesn't get this right.
See:

b4b6cae2f36d ACPI / platform: use ACPI device name instead of _HID._UID
