Stephen Warren 352580870c ARM: tegra: make all I2C ports open-drain 
I2C protocol requires open-drain IOs. Fix the Dalmore and Venice2 pinmux
tables to configure the IOs correctly. Without this, Tegra may actively
drive the lines high while an external device is actively driving the
lines low, which can only lead to bad things.
