Tegra 3 support

Ok, this one took me a little longer than I would have wished for, but now it's good enough to post.

This series adds support for the Tegra 3 line of SoCs. This includes a clock driver that sets up the PLLs and peripheral clocks and a pinctrl driver to bring the external muxing into a sane state.

There is still a lot to do here, but with this series barebox starts up on an NVidia Beaver board and the eMMC is usable.

Next step would be to integrate BCT writing into the Tegra image process so barebox is able to write itself to MMC as a bootable image.

Lucas Stach (18):
gpio: tegra: remove dead code

tegra: add Tegra3 mem initcall
tegra: recognize T30 in debug UART code
dt-bindings: add pinctrl-tegra.h
pinctrl: tegra: add Tegra3 driver
dt-bindings: add tegra30-car.h
clk: tegra: consider new T30 clock registers

ARM: tegra: add basic Tegra3 DT
ARM: tegra: add NVidia Beaver board support
ARM: dts: tegra: add full Beaver pinmux
defconfig: tegra: add some useful options
