bus: mhi: pci_generic: Add mru_default for Cinterion MV31-W
commit 05daa805a86c831ad9692f6f15e1b877c8f10638 upstream.
For default mechanism, product would use default MRU 3500 if
they didn't define it. But for Cinterion MV31-W, there is a known
issue which MRU 3500 would lead to data connection lost.
So we align it with Qualcomm default MRU settings.
