Yeah, while the ->add_pin_ranges() shouldn't be used by DT drivers,
this one requires it to support quite old firmware descriptions that
do not have gpio-ranges property.

The change allows to clean up GPIO library from OF specifics.
There is no functional change intended.

The ->add_pin_ranges() is supposed to be called for the backward
compatiblity on Device Tree platforms or non-DT ones. Ensure that
by checking presense of the "gpio-ranges" property.

This allows to clean up a few existing drivers to avoid duplication
of the check.
