images-swu: Fix swu package creation

See merge request !24

Now the swu package for the corresponding image-*swu contains all necessary
update files and configuration.

For this all swupdate-*img recipes are obsoleted (but currently kept for
compatibility)

linux-stm32mp: Fix admatec 5 inch DPI display parameters

See merge request !23

Various improvements

See merge request !22

Fix dsi clock configuarion in CubeIDE ioc file. With the wrong settings and
DSI enabled, the CubeIDE clock tree validation fails. To quiet this warning,
the clock setting is adapted.
These settings do not have any impact for a running linux system, because
these clocks are calculated correctly by the drivers on the fly.

Link some essential drivert into kernel image to accelerate display
initialisation. Also remove some unused drivers.

gstreamer1.0-plugins-base: Fix OpenGL setup by enabling GBM

See merge request !21

With no window manager like X11 or Wayland available, we need
to use the GBM backend in order to use OpenGL with GStreamer.
Enabling it prevents a build error with gstreamer1.0-plugins-bad
which expects the gstreamer-gl module to be avialable when opengl
is enabled in DISTRO_FEATURES.

Use new override syntax everywhere

See merge request !20

This is not required in Dunfell, but in later releases it is and using it
in Dunfell makes backporting patches from future versions easier.

The changes were made using the script scripts/contrib/convert-overrides.py
from poky (master) and some manual corrections.

Add LVDS and HDMI support for Kontron BL boards

See merge request !14

Support for the following LVDS displays is added on
Kontrons BL boards (stm32mp-t1000-k):
- Jenson JT60050 LVDS 7 inch (stm32mp-t1000-k-70) and
- Jenson JT60180 LVDS 10 inch (stm32mp-t1000-k-101)

HDMI is activated by default for the non-LVDS BL device tree
configuration stm32mp-t1000-k. Due to limitations of clock
settings only a few HDMI monitors will work!
