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 Change-Id: I8b1b3143174584a93f3d45bf482b8922b3f0ec12 Signed-off-by: Daniel Kurtz <djkurtz@chromium.org> Reviewed-on: https://review.coreboot.org/23233 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Marc Jones <marc@marcjonesconsulting.com>
