[ Upstream commit4efc851c36] Currently the EXIU uses the fasteoi interrupt flow that is configured by it's parent (irq-gic-v3.c). With this flow the only chance to clear the interrupt request happens during .irq_eoi() and (obviously) this happens after the interrupt handler has run. EXIU requires edge triggered interrupts to be acked prior to interrupt handling. Without this we risk incorrect interrupt dismissal when a new interrupt is delivered after the handler reads and acknowledges the peripheral but before the irq_eoi() takes place. Fix this by clearing the interrupt request from .irq_ack() if we are configured for edge triggered interrupts. This requires adopting the fasteoi-ack flow instead of the fasteoi to ensure the ack gets called. These changes have been tested using the power button on a Developerbox/SC2A11 combined with some hackery in gpio-keys so I can play with the different trigger mode [and an mdelay(500) so I can can check what happens on a double click in both modes].
