The device tree source files of at91sam9g20ek and at91sam9260ek boards are copied from the Linux v4.10, do the changes below. - Fix the build error for the usb0 node. - Add the reg property for the pinctrl node. - Move the gpio (pioA, pioB, pioC ...) nodes as the pinctrl's slibling nodes, instead of the child nodes. - Add the "u-boot,dm-pre-reloc" property for the dbgu node are used in board_init_f stage. - Add the clk pinctrl of the mmc0 node. - Fix the compilation warnings.
