3c82787359 pinctrl: Use new GPIO_LINE_DIRECTION 
Use newly added GPIO defines GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT instead of using hard-coded 1 and 0.

Main benefit is to make it easier to see which values mean IN and which
OUT. As a side effect this helps GPIO framework to change the direction
defines to something else if ever needed.

Please note that return value from get_direction call on
pinctrl-axp209 driver was changed. Previously pinctrl-axp209 might have
returned value 2 for direction INPUT.

4b024225c4 pinctrl: use devm_platform_ioremap_resource() to simplify code 
devm_platform_ioremap_resource() internally have platform_get_resource()
and devm_ioremap_resource() in it. So instead of calling them separately
use devm_platform_ioremap_resource() directly.

0a6864274e pinctrl: rza2: Include the appropriate headers 
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.
