DT binding maintainers asked to use xnur-gpios instead of xnur-gpio
in the DT binding when converting to YAML (the -gpio suffix is
deprecated in favour of -gpios). This updates the DT files to become
compliant. The Linux kernel driver has already been using gpiod API
when it was added to the kernel, so this change is backwards compatible.

I will extend the description from this patch in v3.
