When updating the irq_chip and msi_domain_ops, the code checkes for already present functions. When more then one ITS controller are present in the system, irq_chip and msi_domain_ops got already set and a warning is invoked. This patch deletes the warning, as the funtions are just already set to the needed callbacks.
