[POWERPC] bootwrapper: Add CONFIG_DEVICE_TREE 



This provides a way to tell the bootwrapper makefile which device tree to
include by default.  The wrapper can still be invoked standalone to wrap
with a different device tree without reconfiguring the kernel, if that is
desired.

The user will only be asked to provide a device tree if the platform
selects CONFIG_WANT_DEVICE_TREE.

	help

	  This specifies the device tree source (.dts) file to be

	  compiled and included when building the bootwrapper.  If a

	  relative filename is given, then it will be relative to

	  arch/powerpc/boot/dts.  If you are not using the bootwrapper,

	  or do not need to build a dts into the bootwrapper, this

	  field is ignored.



	  For example, this is required when building a cuImage target

	  for an older U-Boot, which cannot pass a device tree itself.

	  Such a kernel will not work with a newer U-Boot that tries to

	  pass a device tree (unless you tell it not to).  If your U-Boot

	  does not mention a device tree in "help bootm", then use the

	  cuImage target and specify a device tree here.  Otherwise, use

	  the uImage target and leave this field blank.
