5gc: Update mobility procedure status

There's no procedure to do direct mobility between GERAN/UTRAN and 5GS
according to spec, and IP preservation is not supported either through
indirect mobility GERAN/UTRAN<->EUTRAN<->5GS.

Regarding 3GPP TS 23.502 Annex G, open5gs-smfd supports Gn interface but
only when working against a 4G MME, not through 5GS (PCF and AMF).

Related specs:
*3GPP TS 23.501:
** 5.17.2.4 Mobility between 5GS and GERAN/UTRAN
** Annex L (normative): Support of GERAN/UTRAN access
* 3GPP TS 23.502 4.11.5 Impacts to 5GC Procedures
* 3GPP TS 23.632 5.3 5GC-EPC Mobility Scenarios
