It's based on commit fe8e6d0b0e601ca0a63fe768d4b812d5a45a9da7
"arm/dt: Add dtb make rule" from Rob Herring.

With 'make ARCH=arm dtb', it builds Device Tree Blobs for those
platforms enabled by CONFIG.

This patch works against Linaro kernel tree.  But it needs to go
through mainline review before it gets applied.
