Subject: [PATCH] net: usb: qmi_wwan: Add support for Cinterion MV32

There are 2 models for MV32 serials. MV32-W-A is designed
based on Qualcomm SDX62 chip, and MV32-W-B is designed based
on Qualcomm SDX65 chip. So we use 2 different PID to separate it.

Test evidence as below:
T:  Bus=03 Lev=01 Prnt=01 Port=02 Cnt=03 Dev#=  3 Spd=480 MxCh= 0
D:  Ver= 2.10 Cls=ef(misc ) Sub=02 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=1e2d ProdID=00f3 Rev=05.04
S:  Manufacturer=Cinterion
S:  Product=Cinterion PID 0x00F3 USB Mobile Broadband
S:  SerialNumber=d7b4be8d
C:  #Ifs= 4 Cfg#= 1 Atr=a0 MxPwr=500mA
I:  If#=0x0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=50 Driver=qmi_wwan
I:  If#=0x1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=40 Driver=option
I:  If#=0x2 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=40 Driver=option
I:  If#=0x3 Alt= 0 #EPs= 2 Cls=ff(vend.) Sub=ff Prot=30 Driver=option
