I don't know anything about the uClinux driver -- but in general there is no requirement to have a UART that has an IRQ; its up to how your software is archictected. If your s/w driver polls the UART rather than relying on interrupts, you can just not connect the IRQ in SOPC Builder (specify "NC" instead of an integer in the IRQ field)..
