[PATCH 2/2] ARM: tegra: Move panels to AUX bus

From: Thierry Reding <treding at nvidia.com>
Move the eDP panel on Venice 2 and Nyan boards into the corresponding
AUX bus device tree node. This allows us to avoid a nasty circular
dependency that would otherwise be created between the DPAUX and panel
nodes via the DDC/I2C phandle.
