[PATCH] ARM: tegra: add SD wp-gpios to Venice2 DT

[Stephen Warren]

From: Stephen Warren <swarren at nvidia.com>

Venice2 can detect write-protect on the SD card. Add the required
DT entries to allow this.

Thierry, could you test this for me; my Venice2 has been sent away for
a few days for some rework. You should find that if you write-protect
your SD card, the kernel fails/panics trying to mount it as a r/w root
fs, whereas if the card is not write-protected, everything still works
fine. Thanks.
