[PATCH 10/10] arm/tegra: add support for tegra30 based board cardhu

[Peter De Schrijver <pdeschrijver@nvidia.com>]

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.
