This adds a driver for the AT42QT2120 12 channel capacitive touch sensor IC, (mostly) compatible with Adafruit's MPR121 library.
This library's interface is designed after Adafruit's MPR121 module. The ICs diverge in functionality, so we only include functions available on both chips. To determine which functionality is required, I surveyed several consumers of the MPR121 library. This includes three examples from Adafruit, and many of the projects "dependent" on their library on GitHub. This audit should let us cover enough of the design to use an AT42QT2120 as a drop-in replacement for most users of the MPR121.
