[PATCH 2/2] pinctrl: baytrail: Fix compilation warnings when !CONFIG_PM

[Mika Westerberg <mika.westerberg@linux.intel.com>]

When CONFIG_PM is not set we get following compilation warnings:

 warning: ‘byt_gpio_runtime_suspend’ defined but not used [-Wunused-function]
 warning: ‘byt_gpio_runtime_resume’ defined but not used [-Wunused-function]

Fix this by guarding byt_gpio_runtime_suspend()/byt_gpio_runtime_resume()
with #ifdef CONFIG_PM.
