This modem is a PCIe MBIM modem, found in a lot of modern laptops,
like the Lenovo ThinkPad X1. Unfortunately, oFono does not support
PCIe MBIM modems out of the box, so this patch adds support for them,
as well as MBIM extensions which are needed for newer modems.

Changes from v7:
- Applied changes from Andres Salomon
- Improved the SIM path resolution
- Unified the core logic between mbim_register_{auto,manual}
- Fixed some leaking variables in the MBIM code
- Removed a pointless patch
- Improved comments for the code responsible for resolving the PCI MBIM mod=
