wwan: T8924: add UDEV configuration for USB modeswitch
When using WWAN interfaces, the Linux kernel selects configuration 2 by
default, but that does not work with ModemManager - configuration 3 (MBIM mode)
is a better choice.
Add UDEV rules for Huawei ME906s-158 and HP LT4132 which is a re-brand of
Huawei ME906s-158 to properly set MBIM mode on system startup.
