- use new kernel version with all I2C devices present for testing on 400 kHz bus rate

- cleaned up machine config to be able to add more boards later

- use new kernel with SIS9255 touch support and updated kernel's defconfig

- added vpu firmware to 'linux-firmware' with an bbappend file that is a much cleaner solution than an extra package

- updated kernel version that know comes with a working display

This layer will become the machine only layer and thus will not define
the distro.

Thus remove the distro (but move it to the meta-guf-distro layer).

In order to divide the meta-guf layer into -machine and -distro layers
we need to pull out machine specific packages into the machine
description.

Add the firmware package to the MACHINE_ESSENTIAL_EXTRA_RDEPENDS to
build and install it.

* Split layer into meta-guf-machine and meta-guf-distro

- added first compilable Qt 5.14.1 stack on top of Wayland/using the Wayland backend of Qt5
- it's nearly the same stack from the Zeus evaluation on Wandboard DL with the following exceptions:
  - 'qt5everywheredemo' did not compile, removed for now, will later be added
  - 'qtopcua' did not compile, removed for now, will later be added
- the important points here are:
  - the distro config has to set explicitely eglfs support on qtbase package, otherwise configure does not set the correct GL flags and complains about that
  - the distro config has to set explicitely gstreamer support on qtmultimedia, otherwise configure does not include gstreamer support

- added GPU test programs
- added Weston OS initialization

- added GStreamer to the OS image

- added Big Bug Bunny test video trailer for VPU verification

- added SDMA and VPU firmware from https://github.com/armbian/firmware/raw/master/

- update kernel to new head

- set kernel recipe to crurrent HEAD of GUF linux-stable
- set kernel defconfig to current guf_imx_v6_v7_defconfig
  - with appended device tree enabled
  - with default kernel command line

issue #41059: Kernel Build: removed the GUF support patch, which is obsolete now since we use the kernel from our Git repository now 

issue #41059: Kernel Build: removed dead code in kernel recipe and the GUF support patch, which is obsolete now since we use the kernel from our Git repository now 

The GuF linux kernel port is currently hosted on a private gitlab
account.
It is accessable via git://git@gitlab.com/guf-yocto/stable.git

Thus modify the SRC_URI to fetch from the gitlab repository.

Keep in mind that you need access to the repository using SSH PKI.

The guf setup uses the Dunfell codebase (Yocto version 3.1).
This should be refelcted with the DISTO_VERSION variable.

issue #41059: GUF Yocto documentation: added more documentation about host system preparation and git setup
