Reducing delay in port probing for MBIM modems

Hi Aleksander,

I noticed that mm-port-probe.c:wdm_probe_mbim() delays the MBIM probing by
3s. What issue does the delay try to address?

I'm trying to remove/reduce the 3s MBIM probing delay as well as the 2s
minimum port probe delay (in
mm-plugin-manager.c:mm_plugin_manager_find_device_support()) on a
per-device basis. Suppose the generic plugin is used for many MBIM devices,
is it reasonable to configure these delays via some udev properties?
