sim: check if Fixed Dial is enabled in SIM-card

If SIM-card is inserted, status is checked from EFsst
(is FDN activated) and EFadn (is ADN invalidated).
If USIM-card is inserted, status is checked from EFest
(is FDN activated).

If FD is enabled, halt SIM initialization procedure.
New property (FixedDialing) is added. If FD is enabled,
this has been signalled via DBUS.
