SoC-level changes for tegra and omap

This adds support for the new tegra30 SoC, as well as small
changes to support minor variations of existing omap SoCs.

  arm/tegra: Compile tegra_dt_init_irq only when CONFIG_OF
  arm/tegra: Make MACH_TEGRA_DT depend on ARCH_TEGRA_2x_SOC
  arm/tegra: Delete tegra_init_clock()
  arm/tegra: Fix section mismatch errors in tegra30 pinmux
  arm/tegra: Fix section mismatch errors in tegra20 pinmux
  arm/tegra: refresh defconfig for tegra30
  arm/tegra: add support for tegra30 based board cardhu
  arm/tegra: implement support for tegra30
  arm/tegra: pinmux tables and definitions for tegra30
  arm/tegra: add new fields to struct tegra_pingroup_desc
  arm/tegra: prepare pinmux code for multiple tegra variants
  arm/tegra: rename tegra20 pinmux files
  arm/tegra: generalize L2 cache initialization
  arm/tegra: use PMC reset
  arm/tegra: rename board-dt.c to board-dt-tegra20.c
  arm/tegra: prepare early init for multiple tegra variants
  arm/tegra: don't export clk_measure_input_freq
  arm/tegra: prepare clock code for multiple tegra variants
  arm/tegra: cleanup tegra20 support
