[BUG] Cannot boot Odroid N2+ with 12.0.0 image, official release version or nightly built version

[mood-indigo]

          The image is not "corrupted" but the file path to the dtb files is incorrect. The fix was merged in https://github.com/LibreELEC/LibreELEC.tv/pull/9030 two weeks ago.

Use a current nightly image from https://test.libreelec.tv/12.0/Amlogic/odroid-n2/ .. beware the folder contains old arm images too. You need the latest aarch64 one. Or you can install using LE11 then update to LE12.

I have downloaded all the 12.0.0 images on https://libreelec.tv/downloads/amlogic/ to compare them. They differ only in the extlinux/extlinux.conf file; in particularly the difference is only in the value of the FDT field (except the Odroid-C4 and Odroid-N2 images do not have this field but the FDTDIR field). For example, the FDT value for the NanoPi image is /amlogic/meson-gxbb-nanopi-k2.dtb while the value in the WeTek Play2 image is /amlogic/meson-gxbb-wetek-play2.dtb.

I now suspect the bug is in the script that builds the images; this script does not build a working image for the Odroid N2+ device.

The abovementioned #9030 contains the "remove-amlogic-prefix" patch for the Odroid N2+. So, maybe the build script should lay the odroid-*.dbt file in the topdir instead of the amlogic directory, unlike the images for the other amlogic devices. I am just guessing here.
