arm/tegra: implement support for tegra30 Add support for tegra30 SoC. This includes a device tree compatible type for this SoC ("nvidia,tegra30") and adds L2 cache initialization for this new SoC. The clock framework is still missing, which prevents most drivers from working. The basic IRQs are the same, so remove the dependency on CONFIG_ARCH_TEGRA_2x_SOC.

ARM: tegra: move iomap.h to mach-tegra Nothing outside mach-tegra uses this file, so there's no need for it to be in <mach/>. Since uncompress.h and debug-macro.S remain in include/mach, they need to include "../../iomap.h" becaue of this change. uncompress.h will soon be deleted in later multi-platform/single-zImage patches. debug-macro.S will need to continue to include this header using an explicit relative path, to avoid duplicating the physical->virtual address mapping that iomap.h dictates.

ARM: tegra: match SoC name not board name in DT board files board-dt-tegra*.c should support any board using Tegra when booted using device tree. Instead of explicitly listing all the supported boards, which requires a kernel change for each new board, list the supported SoC model instead. Note that the board files do currently have explicit support for setting up each board's pinmux. However, it's fairly likely that at least the basic devices on any new board will work just fine as set up by the boot- loader, and the pinmux data should be moving into device tree soon anyway.
