[ Impact ]

 * Add plugin to make mbim-cli is able t send AT command to Compal WWAN module for FCC unlock

[ Test Plan ]

 * On the platform with Compal SDX12 WWAN module with ID:
   usb:v413Cp8217
   usb:v413Cp8218
 * Install Compal's WWAN services which is maintained in https://github.com/palcomwireless/linux_pkgs
 * The service can finish FCC unlock with patched libmbim successfully after system boot up
 * The Modem can work with Internet access after valid SIM is plugged

[ Where problems could occur ]

 * It adds new mbim service for supporting Compal module, there is no existing service modification.

 * The mbim relies on transaction task to handle sending AT command to the modem. It will send the command asynchronously, if there is a bug or system issue in GLib, the AT command may not send to modem successfully, and the modem won't work.
