soc/amd: Define post codes
For the most part, this doesn't change any post codes, simply making the
existing post-codes into macros.
picasso/romstage.c did get a couple of post codes removed to match the
other files.
The POST_ROMSTAGE and POST_BOOTBLOCK codes are intended to become global
at some point, while the POST_AGESA and POST_PSP codes would stay AMD
specific.
