From: Thierry Reding <thierry.reding@xxxxxxxxxxxxxxxxx>
Enable host1x, and the HDMI output. Harmony also has a DVI port with an
HDMI form-factor connector, driven by Tegra's LVDS output. This isn't
enabled yet, due to potential issues with having multiple outputs enabled.
Correct DDC I2C frequency to 100KHz.
Add dummy/fixed regulators to satisfy the HDMI driver.
