Rather than printing a warning message in sec_irq_init() due to the missing IRQ number, or returning an error due to a missing irq chip regmap, just return early explicitly. This will become particularly important once errors from sec_irq_init() aren't ignored anymore in an upcoming patch and helps the reader of this code while reasoning about what the intention might be here.
