Telit: increase AT probing timeout for new modules
The AT probing timeout should be increased in all new Telit modules because they may take a long time (even up to 25s) to be usable after the serial ports have been exposed by the kernel.
Currently applicable to all these modules:
- 1040, 1041 LM9x0
- 1050, 1051 FN980
- 1201, 1204 LE910Cx
See issue #260 (closed) for context.
