gemalto: Move atoms to post_online

when the voice call driver is probing, I noticed sometimes
a CME Error with the code = 4 (operation not supported)
related to AT commands "AT+CSSN=1,1" and "AT^SLCC=1".

In the current voice call implementation for Gemalto modems
the ofono_voicecall_create() is called on the gemalto_pre_sim().
The sim is not totaly readed by the module, it is not yet
online which is causing a sporadic problem at driver
intialization also when launching some outgoing/incoming calls.

This change moves the ofono_voicecall_create() to the
gemalto_post_online() to be sure that sim is well registred
and online.  Several other call related atoms are also moved to
post_online state.
