this fixes 3 of 4 mainboards failed by the error on missing IRQ_SLOT_COUNT.
The third, MSI MS9652, creates an IRQ table on the fly, no kidding. Signed-off-by: Stefan Reinauer <stepan@coresystems.de> Acked-by: Stefan Reinauer <stepan@coresystems.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@5322 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
