[PATCH] fix via586 irq routing for pirq 5
Fix interrupt routing for via 586 bridges. pirq can be 5 which needs to be
mapped to INTD. But currently the access functions can handle only pirq
1-4. this is similar to the other via chipsets where pirq 4 and 5 are both
mapped to INTD. Fixes bugzilla #7490
