config: Added Wanhao Duplicator i3 Plus configuration

The Wanhao Duplicator i3 Plus (aka Maker Select Plus,
Microcenter Powerspec Plus, and others) uses an
atmega2560 AVR. The config is based on generic-ramps.cfg
with pin numbers updated from the official Wanhao Marlin
sources at https://github.com/garychen99/Duplicator-i3-plus
