Title:
  Support sending AT commnad by mbim-cli for Compal WWAN module

Status in OEM Priority Project:
  New
Status in libmbim package in Ubuntu:
  Fix Committed

Bug description:
  [ Impact ]

   * Add a service to make mbim-cli be able to 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 inserted

  [ 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.

  [ Other Info ]
