[PULL] irqchip fixes for 4.8-rc4

Hi Thomas, Please find below a handful of fixes targetted at the current cycle. The most important thing is a fix for the trigger configuration on chained irqchip (please see the discussion here[1] for details). The rest is the usual GIC churn, nothing massively critical. Please pull! Thanks,
