Use generic names for the boot scripts for booting from a single
partition and for doing A/B boots from two separate partitions.

Use the generic 'load' command instead of specific filesystem
commands.

Also sync the environment for i.MX6UL/ULL with the one for i.MX8MM.

This way we can boot i.MX8M devices with a boot logo and splash
screen as the display pipeline is available before the userspace and
filesystem are ready.

meta-ked-imx: Update kernel and U-Boot refs

See merge request !27

Replace occurences of 'ktn'/'KTN' with 'ked'/'KED'

See merge request !26

In the future we will reference the BSP as meta-ked-bsp. Adjust names
of layers, files, etc. accordingly. Only some OE metadata like image,
distro or machine override names are keeping the 'ktn' for now.

KED stands for Kontron Electronics Deutschland GmbH where the BSP
is maintained. Nowadays it support only products of the KED branch
and products of the Kontron Europe GmbH or other branches are not
supported.

If bootcfg is unset, the default fit image configuration will be used.

Currently the image build is broken when running it through GitLab CI
with kas base images >3.2.1. Let's pin the image version until we
know how to fix it.

Forward ports for changes from legacy meta-ktn and meta-ktn-imx repo

See merge request sw/ked/meta-kontron!21

FILESEXTRAPATHS_prepend uses old override syntax and is not required
anyway in the base recipe. Remove it and also fix some othe minor
style issues.

This backports the latest libgpiod recipes from meta-oe master. The
new libgpiod v2 includes major changes and improvements and might be
required in certain use cases.

For now the default remains v1.6 while someone who needs the v2 can
set PREFERRED_VERSION_libgpiod = "2.0".

This can be used by WIC or other tools that work with file system images
instead of TAR archives.
