[PATCH 1/4] gpio: tegra: Remove unnecessary check

[Thierry Reding <thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

of_device_get_match_data() can never return NULL, therefore the check
for NULL values is unnecessary.
