soc/amd/stoneyridge: Add CPU files
Copy cpu/amd/pi/00670F00 to soc/amd/stoneyridge and soc/amd/common. This is the second patch in the process of converting Stoney Ridge to soc/. Changes: - update Kconfig and Makefiles - update vendorcode/amd for new soc/ path Change-Id: I8b6b1991372c2c6a02709777a73615a86e78ac26 Signed-off-by: Marc Jones <marcj303@gmail.com> Reviewed-on: https://review.coreboot.org/19723 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>
