[ARM] tegra: initial tegra support

v2: Fixes from Mike Rapoport
	- remove unused header files (mach/dma.h and mach/nand.h)
	- remove tegra 1 references from Makefile.boot

v2: fixes from Russell King
	- remove mach/io.h include from mach/iomap.h
	- fix whitespace in Kconfig

v2: from Colin Cross
	- fix invalid immediate in debug-macro.S

v3:
	- allow selection of multiple boards
