atmodem: Parse optional PLMN parameter of AT+COPS=? result 

The Infineon modem adds an optional <plmn_list> parameter after the
access technology parameter <AcT>. It is not always present, but when
present it makes the operator listing fail.

+COPS: (2,"T-Mobile D","TMO D","26201",0,0),(3,"E-Plus","E-Plus","26203",0,),(3,"Vodafone.de","Vodafone.de","26202",0,),(3,"o2 - de","o2 - de","26207",0,)

Not all networks have this parameter and maybe only the home network
has it anyway. And so far this feature seems to be Infineon specific,
but just in case, parse the parameter if present to make sure the
operator listing is available.
