[PATCH] i2c: tegra: don't open code of_device_get_match_data()

From: Wolfram Sang <wolfram@the-dreams.de>

This change will also make Coverity happy by avoiding a theoretical NULL
pointer dereference; yet another reason is to use the above helper function
to tighten the code and make it more readable.

Compile tested only; HW test would be much appreciated!
