Kerneldevice (generic/udev) updates to support different system bus types

[Aleksander Morgado]

Hey all,

I've been working on several updates to the udev/generic backends in
the kerneldevice object. The main changes are done to better support
non-USB modems (e.g. the new PCI based modules), and most of the
changes are improvements and fixes in the generic backend used e.g. in
OpenWRT, to make it as similar as possible to the udev backend.

The changes are available here:
https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/merge_requests/389

If anyone has PCMCIA or Bluetooth DUN capable devices, I wouldn't mind
specific tests with those when using both generic and udev backends,
especially because I've removed some bluetooth-specific hacks that we
had around and I believe were not completely needed.

Comments welcome!
