To use only PIN management and retrieving IMSI from current sim atom, 
sim type (R-UIM or SIM) has to be specified at atom creation.
The sim type can is determined into Huawei plugin at the same time as 
modem type:
     - If modem type if GSM, sim type SIM.
     - If modem type is CDMA, sim is R-UIM (sim atom is not created in 
case of UIM/ROMSIM)

I was proposing to have those 2 types into include/sim.h.
Thus, sim atom can be flagged as SIM or R-UIM to access or not to the 
file system and use PIN management only e.g. in:
sim_initialize() and sim_initialize_after_pin() we just get the imsi we 
don't try to read the sim file system.

Kind regards,
Guillaume
