Instead of using dtbTool to create a DT image , and include it into the boot
image, we append DTB to the compressed kernel image. the LK bootloader knows how
to retrieve DTB , when they are appeneded to compressed kernel image.
Note:
* it only works with compressed image.
* dtbToo also typically adds msm-ids into the DTB, recent versions of LK exist
that allow a single DTB to be used without the msm-ids, in which case it will
work fine. when using older LK version, it is needed to patch the kernel and
include the msm-ids.

This reverts commit 2f6c73271d440bc78bf4a565df8bc8f0a3563eba. The same kernel
patch is also there in 4.9 stable, and the kernel recipe was upgraded.

The do_compile_append is identical for both kernel recipes,
so move it to the common include file.

Some users need to be able to 'fork' our kernel, so let's make that possible to
do that in .bbappend.
For example:
$ cat meta-foo/recipes-kernel/linux/linux-linaro-qcomlt_%.bbappend
SRCREV="abcdefg"
SRCBRANCH="somebranc-v1.0"
LINUX_LINARO_QCOM_GIT="git://github.com/myproject/qcomlinux.git;protocol=https"

The Yocto Project is very touchy about using 'yocto' instead of 'yocto
project' and it's a linaro vendor tree, not a Yocto Project one.
This does make PV go backwards, but updating the kernel to 4.2.1 or
4.3.x should fix that in the near future.

Instead of requiring the defconfig file to be in SRC_URI, we leave the choice to
the kernel recipe whether it has a local defconfif file, or if it uses a config
file from the git tree directly, which can be specific with an absolute path in
KERNEL_DEFCONFIG variable.
If both the variable is set and the local file defconfig exists in SRC_URI, then
the local file is used.
This commit only adds a new feature, but none of the kernel recipe uses it for now.

We want to reuse the .inc file for more machines, potentially not compatible
between each other.. so let's move the COMPATIBLE_MACHINE definition in the .bb
file directly, and keep the .inc generic.

Since OE-Core:df9975f4 (kernel: Fix non linux-yocto builds) the way
the build of kernel is done has change. Now the source code is moved
placed at STAGING_KERNEL_DIR and the build is done at
${WORKDIR}/build
which is B.
This patch adapts the configure task prepending to cope with those changes, as
well as do_compile_append that was hardcoded to work on ${S}.
Patch largely inspired from:
meta-fsl-arm:f69b21d3 (fsl-kernel-localversion.bbclass: Fix building using out-of-tree)
