From: Chris Morgan macromorgan@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.

From: Chris Morgan macromorgan@hotmail.com

The current panel detection logic crashes when the device boots with mainline A-TF, causing a reboot loop. It turns out mainline A-TF doesn't enable the VO power domain like the BSP A-TF did.

Set the VO domain on and use a memory barrier to ensure it is powered up before we attempt to do the panel detection.
