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:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b4b6cae2f36d92b31788f10816709d5290a1119a
 b4b6cae2f36d ACPI / platform: use ACPI device name instead of _HID._UID
