vc/amd/opensil: add _POC suffix to SOC_AMD_OPENSIL_GENOA

The openSIL code for the Genoa SoC is only a proof of concept, so change
the name of the Kconfig option to include this code in the build from
SOC_AMD_OPENSIL_GENOA to SOC_AMD_OPENSIL_GENOA_POC to clarify that this
is code that isn't intended or ready to be productized.
