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.
