Add support for exynos5250-samsung-nexus10-manta (Google Nexus 10)

This patch series adds initial support for the samsung-manta board, known as Google Nexus 10 to users. The device is powered by
the Exynos 5250 SoC. The notification led driver (as3668) is already in the kernel mailing list and can be found here:

The first two patches add the necessary device tree files and bindings, while the last patch makes a small modification to allow CPU1 to boot, as it requires a call to it's underlying firmware.

This first iteration only provides basic support to get the board up and running and usable via UART. We will upstream additional features in future patches. All patches have been tested on real hardware.
