[PATCH rtems-source-builder 0/1] dtc: Update to 1.6.0

[Christian Mauderer]

Hello,

Joel mentioned in the following thread that the DTC build with RSB is a
bit old:

https://lists.rtems.org/pipermail/devel/2020-April/059026.html

This patch updates it to the latest V1.6.0.

I tested it only with Linux. So we should definitively not merge it
without further feedback. Joel: I think you offered tests on FreeBSD?

Best regards

Christian
