ARM: dts: at91: Add dts files for at91sam9x5ek

The device tree source files of at91sam9x5ek board are copied from
the Linux v4.10, do the changes below.
 - 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 to determine which nodes
   are used by the board_init_f stage.
 - Change the compatible of the spi flash to "spi-flash".
 - Add the spi0 aliases.
 - Fix the compilation warnings.
