Add support for the tegra30 based cardhu development board. Cardhu is a tablet formfactor reference design for tegra30. The patch provides a device tree for the board, updates Makefile.boot to build the dtb, includes the platform in Kconfig and updates board-dt.c.

You should not be adding kconfig entries for boards. They should eventually go away with DT.
