brcm47xx: return the real irq number in bcma_core_irq
The irq signal numbers that are send by the cpu are increased by 2 from the number programmed into the mips core by bcma. Return the irq number on which the irqs are send in bcma_core_irq() now. Signed-off-by: Nathan Hintz <nlhintz@hotmail.com> SVN-Revision: 34669
