This works around a limitation of the chkconfig update-alternatives, so it
works with all our update-alternatives providers.

The for loop already handles the case when KERNEL_DEVICETREE is empty.

Pull out the compilation of the DTB blobs right after the kernel's
own do_compile function finishes. This makes them available just in
time for the kernel image construction functions.

The 3.8 kernel has change the default directory where the dtb file is
stored. The change has been done at:

|     ARM: dt: change .dtb build rules to build in dts directory
|
|     The current rules have the .dtb files build in a different directory
|     from the .dts files. The only reason for this is that it was what
|     PowerPC has done historically. This patch changes ARM to use the generic
|     dtb rule which builds .dtb files in the same directory as the source .dts.

As the Linux kernel, unconditionally, builds the dtc application and
it is the compatible version with the DeviceTree files shipped within
the kernel it is better to use it and the kernel build system to
generate the dtb files.

Some DeviceTree files rely on CPP and kernel headers to be able to
generate the dtb binary contents and it is harder to replicate it
outside of Linux kernel build system so we /use/ it.

To comply with these assumptions we need to use the dtb file when
calling 'make' instead of pointing to the DeviceTree source file; the
code has been made backward compatible but it is advised to move to
the new definition to avoid warnings as:

,----[ Original definition ]
| KERNEL_DEVICETREE = "${S}/arch/arm/boot/dts/imx6q-sabresd.dts"
`----

Becomes:

,----[ New definition ]
| KERNEL_DEVICETREE = "imx6q-sabresd.dtb"
`----

Devicetree files were installed hard-coded in /boot. When KERNEL_IMAGEDEST
is anything else but "boot", the postinstall script and the file locations
no longer match and the postinstall will fail.

Replace "boot" with "${KERNEL_IMAGEDEST}" to fix this problem, and to allow
the devicetree files to be installed in another location.
