SIM/USIM: Add function to get the MNC length from the SIM/USIM

Browse source 
The EF-AD (administrative data) file may contain information about the
length of the MNC (2 or 3 digits) in the IMSI. This can be used to
construct the realm according to 3GPP TS 23.003 during EAP-SIM or
EAP-AKA authentication.
