soc/amd/genoa: rename to genoa_poc
Even though this SoC is called 'Genoa', the openSIL implementation and
the corresponding coreboot integration is only a proof of concept that
isn't fully featured, has known limitations and bugs, and is not meant
for or ready to being productized. Adding the proof of concept suffix to
the name should point this out clearly enough so that no potential
customer could infer that this might be a fully functional and supported
implementation which it is not.
