ARM: dts: at91: Add dts files for at91sam9m10g45ek The device tree source files of at91sam9m10g45ek boards are copied from the Linux v4.10, do the changes as below. - Add the reg property for the pinctrl node. - Move the gpio (pioA, pioB, pioC, pioD, pioE) nodes as the pinctrl's slibling nodes, instead of the child nodes. - Add the "u-boot,dm-pre-reloc" property to determine which nodes are used by the board_init_f stage. - Fix the compilation warnings.
