soc/amd/picasso: Remove ST files not used for PCO

Remove files that aren't needed for the picasso port.

Remove traces of AGESA v5 (includes binaryPI support files).  Remove
SPD helper.

Picasso (and all AMD Family 17h processors) have a very different
boot flow from previous products.  Memory is initialized by the PSP
before the x86 processor is released from reset.  The SPD is read by
the PSP, so it's not needed in coreboot.

TEST=None
BUG=b:130804851
