[ Upstream commit da38ef3e ]

We are currently assuming all GPIOs are non-wakeup capable GPIOs as we
not configuring the bank->non_wakeup_gpios like we used to earlier with
platform_data.

Let's add omap_gpio_is_off_wakeup_capable() to make the handling clearer
while considering that later patches may want to configure SoC specific
bank->non_wakeup_gpios for the GPIOs in wakeup domain.
