of_amba_device_create() uses irq_of_parse_and_map() to translate a DT interrupt specification into a Linux virtual interrupt number. But it doesn't properly handle the case where the interrupt controller is not yet available, eg, when pl011 interrupt is connected to MBIGEN interrupt controller, because the mbigen initialization is too late, which will lead to no IRQ due to no IRQ domain found, log is shown below, "irq: no irq domain found for uart0 !" use of_irq_get() to return -EPROBE_DEFER as above, and in the function amba_device_try_add()/amba_device_add(), it will properly handle in such case, also return 0 in other fail cases to be consistent as before.
