eap: new method API for getting EAP-Identity

Browse Source 
EAP-SIM/AKA/AKA' retrieve the EAP-Identity off the SIM card
not from the settings file. This adds a new EAP method API
which can optionally be implemented to retrieve the identity.
If get_identity is implemented, the EAP layer will use it to
retrieve the identity rather than looking in the settings file.
