modem: use +CEREG to determine EPS network registration status

Browse Source 
This patch adds the support for solicited/unsolicited EPS network
registration status via AT+CEREG, which is configurable via the
'iface-modem-3gpp-eps-network-supported' property of the
MMIfaceModem3gpp interface and is disabled by default.
