sierra: use DHCP for the USB 305 (AT&T Lightning)
For some reason, my AT&T Lightning just doesn't work with static
IP (AT%IPDPADDR) any more. No traffic passes even though everything
is set up the way it was before. No idea what happened. Using
latest firmware 2.0.0.11.
But what's interesting is on Windows the generic Sierra Watcher
app uses DHCP. But on Linux, when using AT%IPDPACT, DHCP doesn't
work. That's odd. But it turns out the modem supports the
"standard" Sierra proprietary AT!SCACT commands, and that
*does* make DHCP work. Crazy no? So since the Windows app
uses DHCP, it's likely that the non-DHCP case (AT%IPDPACT/AT%IPDPADDR)
either isn't well tested or isn't well supported. With that
in mind, let's just use DHCP for this device in Linux too.
Some Sierra modems (e.g. MC7710) will report LTE-specific supported modes in the
AT+WS46=? reply, but not +CLTE capability in the AT+GCAP reply:
AT+GCAP
+GCAP: +CGSM
OK
AT+WS46=?
+WS46: (12,22,25,28,29)
OK

sierra: fix detection of APP1 port
The APP1 port (which has a limited AT parser) doesn't prefix
its replies with <CR><LF> like nice modems do, and that means
it runs afoul of the echo removal bits of the AT serial port
code. We need to parse the whole string even though it's not
prefixed properly to find the APP1 string in the response.
Some sierra modems (e.g. MC7710) have a secondary port that likes to reply OK
to any AT command passed. Detect that as soon as possible, and don't consider
the Icera port probing result from that secondary port.
Different ports of the same modem may get handled by different drivers. We
therefore need to provide a list of drivers (new `Modem.Drivers' property with
signature 'as') instead of just one (removed `Modem.Driver' property with
signature 's').
$ sudo mmcli -m 0 | grep drivers
| drivers: 'qcserial, qmi_wwan'
