Wenyou Yang 110fa9797d ARM: at91: dt: add dts files for sama5d3xek board
Add the device tree files for sama5d3xek board.

The dts files are copied from Linux-4.9, do the changes as below.
 - add reg property for the pinctrl node.
 - move the gpio nodes (pioA, pioB, pioC ...) as the pinctrl's
   slibling nodes.
 - add the "u-boot,dm-pre-reloc" property to determine which nodes
   which are needed by SPL and by the board_init_f stage.
 - fix the compile warning.
 - add spi0 node aliases.
