bus: mhi: pci_generic: Add mru_default for Foxconn SDX55

Browse source 
commit a0572cea88 upstream.

For default mechanism, product would use default MRU 3500 if
they didn't define it. But for Foxconn SDX55, there is a known
issue which MRU 3500 would lead to data connection lost.
So we align it with Qualcomm default MRU settings.
