From: Chris Morgan <macromor...@hotmail.com>
Refactor the board detection logic (again) to make it compatible with
the upstream device-trees, and switch to OF_UPSTREAM.
Now the device boots with the device-tree for the 353P, and then
loads the correct device tree (of 10) in the later stages of SPL.
