ARM: dts: Add dts files for sam9x60ek

add device tree files for sam9x60ek board with below changes.

- Add initial device nodes (pmc, pinctrl, sdhc, dbgu & pit)
- Add the reg property for the pinctrl node.
- Add the "u-boot,dm-pre-reloc" property to determine which nodes
  are used by the board_init_f stage.
