bcma: make it possible to specify a IRQ num in bcma_core_irq()
This moves bcma_core_irq() to main.c and add a extra parameter with a number so that we can return different irq number for devices with more than one. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
