Gabriel Valcazar e19724efcd freescale-layer: remove upstreamed imx recipes and modifications
Back in Yocto 4.0, we applied some imx recipe changes exclusively for the
ccimx93 from meta-imx's rel_imx_6.1.55_2.2.0 tag, but now these changes have
been upstreamed in the meta-freescale scarthgap branch. Since there currently
isn't an NXP BSP based on scarthgap, make all platforms use the upstreamed
versions of the recipes, which are the same versions or newer as the ones
available in meta-imx

Remove the recipes for:
    * firmware-ele-imx
    * gstreamer1.0-plugins-bad
    * gstreamer1.0-plugins-base
    * gstreamer1.0-plugins-good
    * gstreamer1.0-plugins-good

    * libdrm
    * linux-imx-headers
    * optee-test
    * wayland
    * wayland-protocols
    * weston
    * xwayland

Apply these changes:
    * Remove ccimx93-exclusive changes in gstreamer1.0-meta-base
    * Modify imx-gst1.0-plugin bbappend so the upstream version is used in all
      platforms
    * Remove imx-alsa-plugins bbappend so the upstream version is used in all
      platforms
    * Remove firmware-nxp-wifi bbappend since the files we need to install seem
      to already be included in the meta-freescale recipe
    * Remove imx-test and imx-lib bbappends since our custom changes have
      already been included in the meta-freescale recipes

David Escalona 1de1fae447 stm32mpu-ai: add external delegate library to use NPU
Actually, the NPU demos were not making use of the NPU, just the CPU. To enable the NPU usage,
it is required to add the external delegate library 'tflite-vx-delegate'to the system. This is
done by forcing 'tensorflow-lite' to depend on it for the CCMP2 platform, which also requires
'tim-vx' library as a build dependency.

Both the 'tflite-vx-delegate' and 'tim-vx' recipes have been verbatim copied from the ST Beta
branch, using commit with SHA256: 68686850c75061f1c7c4e756a313a41ca810f6ae

- Set camera resolution to 640x480px and center the image.
- Adapt home folder to 'root' user instead of 'weston'.
- Adapt package group to include the new samples and remove the old ones.
- Fix a couple of errors with models download and include them manually.
- Add a runtime dependency with 'libdrm-tests' as the 'modetest' binary is required.

David Escalona f04581b9a6 eiq-examples: extend recipe to download and transform models in the host
Until now, the recipe only installed the binaries and some scripts in the target device. Then,
user had to execute an script in the running system to download and transform the models for
the demo, a process that could take up to 30 minutes. Also, a custom script was required to
acomodate the environment settings before executing any demo. All of this was preventing us from
creating out-of-the-box images including NPU demos for exhibitions and clients.

With the new changes, the recipe now downloads and transforms all the models in the host machine,
saving around 27 minutes and leaving the demos in the target ready to be executed. To ease the
process, a launch script is included for all the demos to configure the environment as well as an
auto-start service.

Gabriel Valcazar fd35a3149e weston: include NXP patch to enable cursor without having to move the mouse
This is an NXP change that reverts a mainline weston commit form v9.0.0, in
which the mouse cursor only gets activated when there is mouse movement. This
change was only being included in the weston v10.0.X i.MX forks.

For platforms that don't use these weston forks (ccimx93 uses the v11.0.X fork
and ccmp15 uses mainline weston), the mouse cursor doesn't load right away when
booting the system, which causes apps that are automatically launched (such as
the LVGL demo) to not register the mouse, rendering said apps unresponsive to
it.

Port NXP's change to all of the weston versions we currently use to avoid this
problem.

Javier Viguera 4d8be061f0 ccimx93: update graphics package for NXP release lf-6.1.55-2.2.0
Backport of graphics package for ccimx93 from NXP's Mickledore-based
lf-6.1.55-2.2.0 release. Mainly copies and appends of graphics recipes
from the new release, and restricted to ccimx93 by changing the
COMPATIBLE_MACHINE, so it does not affect other platforms.
