temp/ofono: implement DTMF in qmimodem driver
Wanted to share, here's the higher level issue: https://invent.kde.org/plasma-mobile/plasma-dialer/-/merge_requests/32
And here's the similar ubports PR: https://github.com/ubports/ofono/pull/17
Found the patch here https://github.com/scintill/android_external_ofono/commit/306a3a6f19546b7b9b6b8df973d75710ce21bc3c (big thanks to the author Joey Hewitt!) and tested it with Plasma Mobile from Manjaro ARM, working for me with PinePhone Braveheart.
