Move amd/stoneyridge/include/amd_pci_int_defs.h to include/soc/

Move src/soc/amd/stoneyridge/include/amd_pci_int_defs.h to
src/soc/amd/stoneyridge/include/soc/.

After much discussion, src/soc/amd/stoneyridge/include/soc is probably
the best location. It was found that there are other common code that
include headers from this folder.
