- Support device tree overlay to modify peripherals states. By using
this feature, we can select the peripheral state like on/off.
-To use this feature, you should change a "overlays" value of env.ini files.

This patch adds support of vendor sub directories for dtb files.
Subdirectories can be specified in $(dts-dirs). Kbuild traverses over
all directories while building and installing dtb files. The directory
tree is also reflected in the install path.

No other kernel installation target moves the target directory out of
the way, even deleting an old version of it. These are destructive
operations, ones which the kernel build system should not be making.
This behaviour prevents being able to do:
make install INSTALL_PATH=/some/path/boot
make dtbs_install INSTALL_DTBS_PATH=/some/path/boot
As it causes the boot directory containing the kernel installed in
step 1 to be moved to /some/path/boot.old. Things get even more fun
if you do:
make install dtbs_install INSTALL_PATH=/some/path/boot INSTALL_DTBS_PATH=/some/path/boot
The kernel gets installed into /some/path/boot, then the directory gets
renamed to /some/path/boot.old, and a new directory created to hold the
dtbs. Even more fun if you supply -j2 when we end up with races in
make.
Remove this behaviour.
If this behaviour is required at installation time, this should be
done by the installation external to the kernel makefiles, just like
it would be done for 'make modules_install'.

This commit actually has no impact because $(src) and $(obj) point
to the same path, but $(src)/Makefile looks better when we include
source files.

The "MAKEFLAGS += --include-dir=$(srctree)" line in the top Makefile
allows us to do this.

Move dtbs install rules to Makefile.dtbinst. This change is needed to
implement support for dts vendor subdirs. The change makes Makefiles
easier and smaller as no longer the dtbs_install rule needs to be
defined. Another advantage is that install goals are not encoded in
targets anymore (%.dtb_dtbinst_).
