ARM: tegra: Core SoC changes for v4.5-rc1

The big thing here is Tegra210 support, which is really only the Kconfig
symbol. Other than that there's a few miscellaneous fixes.

* tag 'tegra-for-4.5-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux:
  ARM: tegra: select USB_ULPI from EHCI rather than platform
  ARM: tegra: Ensure entire dcache is flushed on entering LP0/1
  amba: Hide TEGRA_AHB symbol
  soc/tegra: Add Tegra210 support
  soc/tegra: Provide per-SoC Kconfig symbols
