Add the device tree files for sama5d4 Xplained board. The dts files are copied from Linux-4.4, do the following changes. - add reg property for pinctrl node. - move the gpio nodes(pioA, pioB, pioC ...) from the pinctrl child's nodes to its 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 compilation warnings.
