[coreboot] v2[PATCH]RCA RM4100 irq routing fixes

Quoting Uwe Hermann :

You got it. Another irq routing issue. What a pain in the arse. Here I  
am thinking it was something much more. So, with the irq_tables.c I  
originally submitted I tried to make it better than the original but  
it just keeps having issues. So here is a patch with the irq_tables.c  
dumped from the original bios, it may look funky  but everything works  
good (including all USB devices) :-)
