samsung: split initialization sequence to ensure echo is off

Browse Source 
Split the Samsung initialization sequence from "ATZ E0 V1" to "ATZ"
and "ATE0 V1" - the modem is allowed to ignore the rest of the line
after Z, so echoing was not being turned off, leading to getting
"AT+CIMI\n\n" as part of the IMSI when it is retrieved at startup.
