soc/amd/picasso: Remove all AGESA references

Family 17h will not use the Arch2008 (a.k.a. v5) wrapper.  Remove
all source, support functions, and comments related to AGESA.

Family 17h requires v9 which has no similarities to v5 for
integration into a host firmware.  AGESA v9 support will be added
via subsequent patches into the appropriate locations.
