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/.
