[PATCH] pinctrl: rza2: Include the appropriate headers

[Linus Walleij <linus.walleij@xxxxxxxxxx>]

This driver is implementing a GPIO driver so include
<linux/gpio/driver.h> and not the legacy API <linux/gpio.h>.
When testing it turns out it also relies on implicit
inclusion of <linux/io.h> (readw etc) so make sure to
include that as well.

Geert: assuming you will pick this up if you're happy
with it.
