Add ATxmega common files and cpu definitions. This works was originally developed by @Josar. The 2018 version were port to 2021 mainline. This version changes original port to have only the atxmega CPU definition. With that, all family can be accomodated. Signed-off-by: Gerson Fernando Budke <nandojve@gmail.com>
