 summary says it all. patch attached. minor changes, but want to run them
 by the owner first.

 I want to deprecate qwt 5.1.2 and move the 'qwt' port to the latest 5.2
 series, to match up with how the QWT project is handling their repos
 (latest 5 and latest 6). If this port is compatible with qwt6+, then I'd
 recommend adding in a variant to handle selection (I didn't test this, one
 way or the other). This is the last port that I can find that requires
 'qwt' only -- QMK-Groundstation has a variant for this (qwt 5.1 or qwt
 5.2), which I will request removal of the former & using qwt52 only.
