Subject: [PATCH] mhi: pci_generic: add support for sc8280xp-crd SDX55 variant

The SC8280XP Compute Reference Design (CRD) has an on-PCB SDX55 modem
which uses MBIM.

The exact channel configuration is not known but the Foxconn SDX55
configuration allows the modem to be used so reuse that one for now.
