Huawei ME906S: Trying to fix GPS support

Hi.

I am searching for a help to fix the GPS support for my modem Huawei
ME906S for Lenovo Thinkpad. ModemManager-1.12.6 (and all earlier) GUI
says that GPS Location is Not supported.

It surely is. Looking at
ModemManager/plugins/huawei/mm-broadband-modem-huawei.c, I see that
AT^WPDGP should turn GPS on. Also the modem AT command reference
confirms that.
http://download-c.huawei.com/download/downloadCenter?downloadId=51047&version=120450&siteCode

And indeed, it turns on the GPS:

Here is a protocol from /dev/ttyUSB0 115200
AT^WPDGP
OK

... After some time, I will get a fix. Even gpsd works correctly on
these data.

There is a behavior difference between openSUSE Leap 15.0 and 15.2. In
15.0, there were 1 to 4 ttyUSB? devices (depending on the modem state)
and AT^WPDGP had to be sent to ttyUSB0, but NMEA output appeared in ttyUSB3.
In 15.2, there is only one ttyUSB0. AT^WPDGP is sent to ttyUSB0, and the
NMEA output appears in ttyUSB0 as well.
