Ashok Raj f4cc36066a PCI: Program MPS for RCiEP devices 
commit aa0ce96d72dd2e1b0dfd0fb868f82876e7790878 upstream.

Root Complex Integrated Endpoints (RCiEPs) do not have an upstream bridge,
so pci_configure_mps() previously ignored them, which may result in reduced
performance.

Instead, program the Max_Payload_Size of RCiEPs to the maximum supported
value (unless it is limited for the PCIE_BUS_PEER2PEER case).  This also
affects the subsequent programming of Max_Read_Request_Size because Linux
programs MRRS based on the MPS value.

Fixes: 9dae3a97297f ("PCI: Move MPS configuration check to pci_configure_device()")
