We need to add "clean-files" in Makfiles to clean up DT blobs, but we
often miss to do so.

Since there are no source files that end with .dtb or .dtb.S, so we
can clean-up those files from the top-level Makefile.

dts/Makefile is called only for simpleImage target
which is causing that *.dtb are not removed.
This patch fix it.

Currently the linux.bin target creates both linux.bin and linux.bin.ub.
Add linux.bin.ub as separate target to generate linux.bin.ub.

The current rules have the .dtb files build in a different directory
from the .dts files. This patch changes microblaze to use the generic dtb
rule which builds .dtb files in the same directory as the source .dts.

This requires moving parts of arch/microblaze/boot/Makefile into newly
created arch/microblaze/boot/dts/Makefile, and updating
arch/microblaze/Makefile to call the new Makefile. linked_dtb.S is also
moved into boot/dts/ since it's used by rules that were moved.

All ARCHs have the same definition of MKIMAGE. Move it to Makefile.lib
to avoid duplication.

All ARCHs have similar definitions of cmd_uimage. Place a sufficiently
parameterized version in Makefile.lib to avoid duplication.

When building with latest binutils, vmlinux includes
some sections which need to be stripped out when building
the binary image.

This hooks dtc into Kbuild's dependency system.

Thus, for example, "make dtbs" will rebuild tegra-harmony.dtb if only
tegra20.dtsi has changed yet tegra-harmony.dts has not. The previous
lack of this feature recently caused me to have very confusing "git
bisect" results.

For ARM, it's obvious what to add to $(targets). I'm not familiar enough
with other architectures to know what to add there. Powerpc appears to
already add various .dtb files into $(targets), but the other archs may
need something added to $(targets) to work.

'make clean' does not to delete the following build generated file:
	arch/microblaze/boot/linux.bin.ub

'make mrproper' does not to delete the following build generated files:
	arch/microblaze/boot/simpleImage.*

Fix the Makefile to delete these build generated files.

See [1] for a discussion on why simpleImage.* files are deleted with 'make
mrproper' and not with 'make clean'.

Two version are generated.
linux.bin.ub which is created from linux.bin file
and
simpleImage.<dts>.ub which is created from stripped simpleImage.<dts> file

Load address and entry point is for microblaze first instruction
which is CONFIG_KERNEL_BASE_ADDR variable.

There is possible for simpleImage format parse _start symbol too.

simpleImage.<dts> is still stripped elf file

I cleared simpleImage.<dts>.unstrip file because there are so big.

Instead of remembering to specify DTB= on the make commandline, this commit
allows the much friendlier make simpleImage.<dts>
where <dts>.dts is expected to be found in arch/microblaze/boot/dts/
The resulting vmlinux, with the compiled DTS linked in, will be copied to
boot/simpleImage.<dts>

This mirrors the same functionality as on PowerPC,
albeit achieving it in a slightly different way.

+ strip simpleImage file
The size of output file is very similar to linux.bin.

vmlinux - full elf without fdt blob
simpleImage.<dtb name>.unstrip - full elf with fdt blob
simpleImage.<dtb name> - stripped elf with fdt blob
