[PATCH v4 11/13] ARM: dts: microchip: add support for sama7d65_curiosity board

[Ryan.Wanner at microchip.com]

From: Romain Sioen <romain.sioen at microchip.com>

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.
