Thierry Reding 3227166c3b drm/tegra: dpaux: Configure pads as I2C by default 
The DPAUX code paths already configure the pads in AUX mode, but there
is no way to reconfigure them in I2C mode for HDMI (the DPAUX module is
unused in that case). Enabling the pads in I2C mode by default is the
quickest way to support HDMI. Eventually this may need an explicit call
in the user drivers.

Thierry Reding 1ca2030563 drm/tegra: dp: Support address-only I2C-over-AUX transactions 
Certain types of I2C-over-AUX transactions require that only the address
is transferred. Detect this by looking at the AUX message's size and set
the address-only bit appropriately.
