pinctrl: bcm2835: Switch to use ->add_pin_ranges()

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.
