sim: Add SIMCOM specific PIN retry handling

Use AT+SPIC for obtaining retries remaining for SIM PIN / PUK

AT+SPIC Retries Remaining to Input SIM PIN/PUK

+SPIC: <pin1>,<pin2>,<puk1>,<puk2>

Parameters
<pin1> Times remained to input chv1
<pin2> Times remained to input chv2
<puk1> Times remained to input puk1
<puk2> Times remained to input puk2
