Should only be enabled in the new Landingship config. Will fix.

Actually there's two IR receivers:
- one on the geekbox module (on the bottom side)
- and another one on the landingship.

Both are connected to the same GPIO pin, so you can keep it enabled in the main geekbox dts.

About the pinctrl, same remark as for gpio-keys: there's already external pull-up resistors on this pin, so it should be better to use pcfg_pull_none instead of pcfg_pull_up.

Julien

P.S. See Heiko, two bugs in the new nodes already, glad I have them
separate. :)
