From: Romain Sioen <redacted> Add device tree support for the SAMA7D65 Curiosity board. Update the Makefile to include the new device tree file. uart6 is related to flexcom6, hence not sorted in alphabetical order.

While applying this, I switched chosen and aliases to have it alphanumerically sorted.
