cover ARM: tegra: Enable HDMI on Tamonten carriers

The three patches in this series enable the HDMI output on Plutux and TEC. The Medcom-Wide only has an LVDS output and the TEC has an LVDS output as well, but since they depend on the videomode helpers and the power-sequences patch series, they will only be enabled in subsequent patches.

PATCH 1/3 ARM: tegra: tamonten: Add host1x support

Hook up the required regulators, I2C DDC adapter and hotplug detect GPIO to the Tamonten HDMI output. Carrier boards still need to explicitly enable the output to use it.

The three patches in this series enable the HDMI output on Plutux and TEC. The Medcom-Wide only has an LVDS output and the TEC has an LVDS output as well, but since they depend on the videomode helpers and the power-sequences patch series, they will only be enabled in subsequent patches.

Thanks, I've applied the series to Tegra's for-3.8/dt branch.
