ARM: dts: microchip: add support for sama7d65_curiosity board

Browse Source 
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.

[claudiu.beznea: moved chosen node after alias for aphanumerically
 sortage, added a space in front of <PIN_PD19__FLEXCOM6_IO1> for
 alignment]
