gpio: omap: fix error handling in omap_gpio_irq_type

Browse source

The GPIO bank will be kept powered in case if input parameters
are invalid or error occurred in omap_gpio_irq_type.

Hence, fix it by ensuring that GPIO bank will be unpowered
in case of errors and add additional check of value returned
from omap_set_gpio_triggering().
