ARM: dts: exynos: Add TOPEET itop core board SCP package version

The TOPEET itop is a Samsung Exynos4412 core board, which has
two package versions. This patch adds the support for SCP version.

Currently supported are USB3503A HSIC, USB OTG, eMMC, RTC and
PMIC. The future features are in the based board. Also MFC and
watchdog have been enabled.
