commit 1ac698790819b83f39fd7ea4f6cdabee9bdd7b38 upstream.

These modules have 2 different USB layouts:

The default layout with PID 0x9205 (AT+CUSBSELNV=1) exposes 4 TTYs and
an ECM interface:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  6 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9205 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 1 Cls=02(commc) Sub=06 Prot=00 Driver=cdc_ether
  I:  If#=0x5 Alt= 1 #EPs= 2 Cls=0a(data ) Sub=00 Prot=00 Driver=cdc_ether

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: AT-capable port (data).

In the secondary layout with PID=0x9206 (AT+CUSBSELNV=86) the module
exposes 6 TTY ports:

  T:  Bus=02 Lev=01 Prnt=01 Port=02 Cnt=01 Dev#=  8 Spd=480 MxCh= 0
  D:  Ver= 2.00 Cls=02(commc) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
  P:  Vendor=1e0e ProdID=9206 Rev=00.00
  S:  Manufacturer=SimTech, Incorporated
  S:  Product=SimTech SIM7080
  S:  SerialNumber=1234567890ABCDEF
  C:  #Ifs= 6 Cfg#= 1 Atr=e0 MxPwr=500mA
  I:  If#=0x0 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x1 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x2 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x4 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=ff Driver=option
  I:  If#=0x5 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=option

The purpose of each TTY is as follows:
 * ttyUSB0: DIAG/QCDM port.
 * ttyUSB1: GNSS data.
 * ttyUSB2: AT-capable port (control).
 * ttyUSB3: QFLOG interface.
 * ttyUSB4: DAM interface.
 * ttyUSB5: AT-capable port (data).
