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.

[nicolas.ferre@microchip.com:
- fix gclk,
- fix pio/pinctrl controller definition and allow to have more
than only PIOA for this SoC,
- removing pinctrl address]

[claudiu.beznea@microchip.com:
- use SAM9X60's compatible for pinctrl
- add drive strength and slew rate options for SDMMC0 pins.]

[tudor.ambarus@microchip.com:
- u-boot,dm-pre-reloc property in dedicated file,
- fix pit len, starts from 0xFFFFFE40 and it is of len 0x10]
