For the older kernels (5.10) the build of dtbo's is not supported in the
kernel, so overlay.dtb is used here. This change allow to fallback to
the old naming when search for the detected overlays.

The Flash-N-Go System bootscript should also check for an additional
custom bootscript and run it if one was found.

The bootscript checks now if the cpu_temp_grade var is set in the u-boot
environment. If so, the scripts tries to load the corresponding overlay.
According to the u-boot cpu_get_temp_grade function, the critical extended
commercial temp is equal to the industrial temp. Therefore, the industrial
overlay is also applied for the extended commercial grade.
Deploy industrial temp overlay for mx8mp and mx8mm. The automotive overlay
is not deployed, since mx8mp and mx8mm SoCs are only available in consumer
and industrial versions at the moment.
The default values in devicetree match the consumer/commercial grade.

This commit
- installs baseboard version information into the /version node of the
devicetree
- installs module version information into the /version node of the
devicetree
- installs the u-boot version into the /version node of the devicetree

The output used '' but we want to see the loaded variables so
"" is needed.

For tanaro a bootscript for u-boot is needed.
Use install scripts also for tanaro.
