For folks not using concatenated device tree with uImage, having an handy function to find and load device tree is very handy.
So introduce findfdt and loadfdt and run findfdt by default to make it easier on user scripts.

Lets add the detection of xMD and along with that we add omap3-beagle-xm.dtb detection - makes sense? OR do we assume all un-matched devices default to beagle xMD? what if there was a vanilla beagle rev D?
