If GPIO hog configuration failed while adding OF based

This helps of properly handling the gpio driver dependency.
When adding the gpio hog nodes for NVIDIA's Tegra210 platforms,
the gpio_hogd() fails with EPROBE_DEFER because pinctrl is not
ready at this time and gpio_request() for Tegra GPIO driver
returns error. The error was not causing the Tegra GPIO driver
to fail as the error was getting ignored.

Oops is this something I should apply for fixes and tag
for stable?
I dont think that it is needed for stable as this is newly added feature.
