device/pciexp: Match Max_Payload_Size between ends of a link
Ends of a PCIe link may advertise different Max_Payload_Size in
their PCIe Express Capabilities, Device Capabilities block.
For correct operation, both ends of the link need to have their
Device Control Max_Payload_Size programmed to match and not
exceed the other end's Device Capabilities.
