Yes, for the gpio_dev_attr

I merged these two patches because of a comment to introduce
new variables/structures only in the patch where they are used.
Since "omap_gpio_dev_attr" is being used by hwmod DB I merged
these two patches. Do you think that hwmod DB patches should not
be merged with other patches?
