dell: speed probing time up and reduce udev dependency
Currently Dell plugin implements a retry logic of three commands
(AT+GMI, AT+CGMI, ATI1I2I3) to detect modem's vendor string.
Moreover, since Telit modems always reply to the first command, to speed
the probing time up, those modem are tagged with an Udev rule so that we
can avoid sending the other two commands at all.
However, the retry logic is in case a port needs some time to reply, so
it makes sense to apply it only to the first command. Then if the port still
does not respond with any kind of reply, that probably means that it is not
AT capable and we can skip the other AT commands as well.
Then, this patch:
- sets a maximum number of timeouts for AT+GMI to 3. After this
timeouts, the port is considered not AT-capable.
- sets AT+CGMI and ATI1I2I3 to be sent only once.
- removes Dell udev rule for tagging Telit Modems.
