Kuk had a version of the bl31.bin add to the mkimage repo, but the yocto
way to handle it, is to build it using the imx-atf recipe.
Removing this overrides let imx-boot copy the files from the common
deploy directory again.

The tools recipes still use SSH as protocol for the checkout.
Since we have opend our repository to the public, SSH isn't available
anymore. Because of this, we switch to HTTPS as protocol.

The URL for the imx-mkimage was outdated.
Updated the config to our new Git server (git.seco.com).

The recipes in the dynamic layer haven't been updated by the conversion
script.

* Conversion of the OVERRIDE syntax
* New folder names for NXP specific folders

For NXP changes see the new MACHINE_OVERRIDES mechanism

The file was called fw_env.conf which is not read by fw_printenv

As the number of files needed to install imx-boot/u-boot grows, all
files are packaged into a tar to be extracted during installation.

Add machine conf.
Adapt u-boot branch for new machine.
Adapt imxmkimage branch for new machine.
Adapt kernel receipe.

* for IMX8(M) the u-boot binary itself needs to be packed together with
the u-boot SPL binary, DDR firmware, SCU firmware and ATF firmware. For
this meta-freescale offers the imx-boot recipe.
* the imx-mkimage from Keith und Koep already includes some of the
firmwares pre-compiled, so these don't need to be built from source
* add a dynamic-layers structure to allow appending files only when
meta-freescale (freescale-layer) is present, so builds still work with
IMX6, where meta-freescale is not used
* use guf branch of u-boot-imx-kuk
