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.
