[ Upstream commit 7bae48b22c8d38c5cd50f52b6e15d134e2bb3935 ]
The PDC irqchp can convert a falling edge or level low interrupt to a rising edge or level high interrupt at the GIC. We just need to setup the GIC correctly. Set up the interrupt type for the IRQ_TYPE_EDGE_BOTH as IRQ_TYPE_EDGE_RISING at the GIC.
