[PATCH] i2c: tegra: Fix compile when !CONFIG_OF

[Stephen Warren <swarren-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

When !CONFIG_OF, <linux/of.h> doesn't prototype of_get_property(), which
causes i2c-tegra.c to fail to compile. Make the references to this
function conditional to solve this.

Grant, is this the correct way to solve this? Other solutions I can see are:
a) Make ARM or Tegra select CONFIG_OF, now that ARM is moving to Device Tree.
b) Make <linux/of.h> provide dummy inline versions of its functions when
   !CONFIG_OF.
