All the Tegra boards borrow the files from board/nvidia/common/ directory, i.e., board/nvidia/common/* are not vendor-common files, but SoC-common files. Move NVIDIA common files to arch/arm/mach-tegra/ to clean up Makefiles. As arch/arm/mach-tegra/board.c already exists, this commit renames board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c, expecting they will be consolidated as a second step.
