cmake: modules: dts: print stderr on failure

M1cha · M1cha · commit c1fa61057c18 · 2024-10-01T09:32:11.000+02:00
059aae7 actually hid error messages completely instead of making them more visible. db7a390 restored that for some processes, but not for dtc itself. Without this patch, a device tree error like a missing `reg` property failed the build without showing the reason. Signed-off-by: Michael Zimmermann <sigmaepsilon92@gmail.com>
