ARM: dt: change .dtb build rules to build in dts directory
The current rules have the .dtb files build in a different directory from the .dts files. The only reason for this is that it was what PowerPC has done historically. This patch changes ARM to use the generic dtb rule which builds .dtb files in the same directory as the source .dts.
