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.
