linux: factor dts/dtc/dtb handling into a specific include

Richard/Saul,

This fixes BUGID 610, and kicks off a bit of cleaning with the various kernel include files. Patch 1/3 says it all:

[
The powerpc linux-yocto kernels were not creating dtb images in the deploy directories. This was due to two problems:

- the dtb generation rules were not being configured
- the boards were not specifying a device tree in their config

This change addresses the first point by factoring out the dtb generation routines into a new include that can be used by multiple recipes.
]

With these changes I've built and generated a dtb for the mpc8315-rdb.
