The "pciehp_slot_with_bus" option is a workaround for the platforms
that assign the same physical slot number to multiple slots. If your
system has PCI chassis and it supports Chassis Number registers,
maybe one of the solution is using chassis number + slot number as a
slot name. But I don't have any idea other than "pciehp_slot_with_bus"
if your system doesn't support chassis number.

Do you have any idea?

Thanks,
Kenji Kaneshige
