You don't use the UICs to generate an outbound message interrupt so there is no "initialization". There is a hardwired UIC interrupt generated by inbound message interrupts. Since you are talking about writing a basic Linux device driver, I suggest you see one of the many books on the topic to learn some of the basics. request_irq(), for example, is explained with many examples.
