[PATCH V2] ARM: tegra: fix pinctrl misconfiguration on Venic2

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Other boards use PULL_NONE for their debug UART pins, and without this
change, the board doesn't accept any serial input.

Don't set the I2S port pins to tristate mode, or no audio signal will
be sent out.

v2: Added fix for I2S port.

Laxman, can you please go through the whole pinctrl configuration for
Venice2 and make sure it's correct. Perhaps the best approach would be
to compare it against our downstream kernels for this board.
