Mario Scheithauer f5a48989b4 soc/intel/elkhartlake: Make PCIe root port max payload size configurable
The data payload size of PCIe root ports can be set to either 128
(default) or 256 bytes. A bigger payload size can improve PCIe data
throughput on the given port. FSP-S provides a parameter to configure
this value.

This patch provides a chip config so that this FSP parameter can be set
as needed in the devicetree on mainboard level.
