gpio: pl061: use chained_irq_* functions in irq handler
Use chained_irq_enter/exit helper functions instead of direct pointer accesses. This is needed for generic irq chip conversion. Signed-off-by: Rob Herring <rob.herring@calxeda.com> Acked-by: Grant Likely <grant.likely@secretlab.ca> Cc: Linus Walleij <linus.ml.walleij@gmail.com>
