USB: serial: option: add Quectel EM05-G modem

  The EM05-G modem has 2 USB configurations that are configurable via the AT
command AT+QCFG="usbnet",[ 0 | 2 ] which make the modem enumerate with
the following interfaces, respectively:

"RMNET" : AT + DIAG + NMEA + Modem + QMI
"MBIM"  : MBIM + AT + DIAG + NMEA + Modem

The detailed description of the USB configuration for each mode as follows:

This looks much better, thanks!

In the future, when updating a patch you should include a changelog here
below the '---' line and the patch revision should be indicated in the
Subject prefix (e.g. this should have been "[PATCH v3]: USB: serial:
...").

These defines should be sorted by PID.

And you have some stray whitespace after the comma here, which would
have been picked up by scripts/checkpatch.pl which you should run on
your patches before submitting them.

I've fixed up the above nits (sort order and white space) and applied
this one for 6.2 now so you don't need to send a v4 this time.
