Remove AmigaOneG3SE board
The AmigaOneG3SE board has been orphaned or a very long time, and broken for more than 12 releases resp. more than 3 years. As nobody seems to be interested any more in this stuff we may as well ged rid of it, especially as it clutters many areas of the code so it is a continuous pain for all kinds of ongoing work.
