soc/amd/cezanne/fch: add PCIe GPP clock generator configuration settings

I'm not 100% sure if this should rather be duplicated from Picasso or
commonized. Checked with the docs and this won't be compatible with
Stoneyridge and one future product's PPR lacked the corresponding
register. Some other chip has a compatible register layout, but a
different number of PCIe GPP clock outputs, so the common code would
need to use some SoC-dependent defines and possibly a SoC-specific
lookup table for the mapping which is also not that great.
