amd/stoneyridge/include/soc/southbridge.h: Replace SATA magic numbers

CONFIG_STONEYRIDGE_SATA_MODE is compared against "magical numbers".
Because actual literals are in AGESA.h and adding agesa_headers.h to
southbridge.h causes compile errors, move comparison code from southbridge.h
to southbridge.c (where they are actually used). Replace these numbers
with actual literals.
