atmodem: Get strength and tech the quectel way on EC21

I had some trouble getting network strengh and access technology the
standard way on Quectel EC21. It does work - but only kind of. I did not
get URCs when I am sure I should. This way through CIEV, CIND and CMER
is also not documented in Quectel documentation, so I suspect this to be
unsupported.
This is now changed to the "quectelish" way of gettings those values and
this does work more fine-grained and reliable on the Quectel EC21.
