remote-BSS neighbors: allow only one cell ID

I believe I have initially misinterpreted the idea behind sending a Cell
Identifier List in BSSMAP Handover Required messages. Instead of associating N
Cell Identifiers with one ARFCN+BSIC, the idea is to add up N separate
ARFCN+BSIC's Cell Identifiers into a list. To keep the door open for future
code simplification, make sure to allow only one Cell Identifier per remote
ARFCN+BSIC on the VTY UI.
