ARM: at91/gpio: add irqdomain and DT support
Add "legacy" type of irqdomain to preserve old-style numbering and allow smooth transition for both DT and non-DT cases. Original idea and code by Jean-Christophe Plagniol-Villard. Signed-off-by: Nicolas Ferre <nicolas.ferre@atmel.com> Acked-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
