[PATCH 1/2 v3] USB: serial: option: add Lonsung U8300/U9300 product

[PATCH 1/2 v3] USB: serial: option: add Lonsung U8300/U9300 product

[Coia Prant]

Update the USB serial option driver to support Longsung U8300/U9300.

For U8300

Interface 4 is used by for QMI interface in stock firmware of U8300, the
router which uses U8300 modem. Free the interface up, to rebind it to
qmi_wwan driver.
Interface 5 is used by for ADB interface in stock firmware of U8300, the
router which uses U8300 modem. Free the interface up.
The proper configuration is:

Interface mapping is:
0: unknown (Debug), 1: AT (Modem), 2: AT, 3: PPP (NDIS / Pipe), 4: QMI, 5: ADB

For U9300

Interface 1 is used by for ADB interface in stock firmware of U9300, the
router which uses U9300 modem. Free the interface up.
Interface 4 is used by for QMI interface in stock firmware of U9300, the
router which uses U9300 modem. Free the interface up, to rebind it to
qmi_wwan driver.
The proper configuration is:

Interface mapping is:
0: ADB, 1: AT (Modem), 2: AT, 3: PPP (NDIS / Pipe), 4: QMI

Note: Interface 3 of some models of the U9300 series can send AT commands.

Thanks for the update. Next time, remember to include a short changelog
here when revising a patch.

I dropped the product defines in favour of a comment (as they don't
really add any value and we don't have to worry about keeping the
defines sorted).

I also trimmed the commit message slightly before applying.

The end-result is here:
