bcma: gpio: Convert to immutable gpio irqchip
This switches the BCMA gpio irqchip to be immutable. The GPIO subsystem plays
tricks on the irqchip structures, and we're fixing it one driver at a time. See
merge commit 4bde53ab3370 ("Merge branch irq/gpio-immutable into
irq/irqchip-next") for all the details.
Tested on the D-Link DWL-6810AP.
