Hi Stephen,
Thanks for the patch. I have added it to the 'for_next' tree. Max, since
you added that feature for Xtensa, any comments before I ask to pull?

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes xtensa to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.
This requires moving parts of arch/xtensa/boot/Makefile into newly
created arch/xtensa/boot/dts/Makefile, and updating arch/xtensa/Makefile
to call the new Makefile.

This patch applies recent dtc-rule-related changes to the xtensa arch.
They couldn't be applied along with the similar changes for other archs
due to dependencies on other xtensa changes. This should apply OK now to
Linus's tree, or for 3.9.
Note: I have not tested this recently.
