Currently the da9062 GPIO's aren't available. The patch adds the support
to make these available by adding a gpio device with the corresponding
irq resources. Furthermore the patch fixes a minor style issue for the
onkey device.

The DA9062 is a mfd pmic device which supports 5 GPIOs. The GPIOs can
be used as input, output or have a special use-case.
The patch adds the support for the normal input/output use-case.

Changelog:
v3:
- add comment for gpio private include
- add missing bits.h include
- add pin_config state container and set initial pin state to push-pull
- make use of GPIO_LINE_DIRECTION_{IN,OUT}
- update MAINTAINERS entry -> gpio-da90??.c already covered but not
pinctrl-da90??.c
v2:
- fix minor style issue
- move from drivers/gpio to drivers/pinctrl
- Fix spelling issue
- rename local gpio_dir to gpio_mode
- Add datasheet reference and TODO notes
- move gpio to mfd-root node to avoid hierarchical interrupt chips
- Add gpio-controller property check
- remove of_device_id since we drop the gpio of-subnode
- Drop da9062_gpio_get_hwgpio

I can merge this to the pinctrl subsystem but then I need
Lee's ACK on patches 1 & 2 as they are to the MFD subsystem
and I think he will want me to create an immutable branch too?
As Lee is not even on the To: line I think it is unlikely to happen,
so maybe repost, stating your request for his ACK?
Yours,
Linus Walleij

Or any other line I guess? Seeing as these aren't in my inbox.
Yes, please submit a RESEND with me as a recipient.
