MIPS: Create common infrastructure for building built-in device-trees
In preparation for moving the device-trees to a common location, introduce the config option BUILTIN_DTB, which can be selected by platforms that use a device-tree built into the kernel image, and create a Makefile to build the device-trees in arch/mips/boot/dts/.
