irqchip/crossbar: Restore the irq_set_type() mechanism
The conversion of the crossbar irqchip to hierarchical irq domains failed to provide a mechanism to properly set the trigger type of an interrupt. The crossbar irq chip itself has no mechanism and therefor no irq_set_type() callback. The code before the conversion relayed the trigger configuration directly to the underlying GIC. Restore the correct behaviour by setting the crossbar irq_set_type callback to irq_chip_set_type_parent(). This propagates the set_trigger() call to the underlying GIC irqchip.
