The mpic->irq_count variable is only used as a software error-checking limit to determine whether or not an IRQ number is valid. In board code which does not manually specify an IRQ count to mpic_alloc(), i.e. 0, it is automatically detected from the number of ISUs and the ISU size. In practice, all hardware ends up with irq_count == num_sources, so all of the runtime checks on mpic->irq_count should just check the value of mpic->num_sources instead. When platform hardware does not correctly report the number of IRQs, which only happens on the MPC85xx/MPC86xx, the MPIC_BROKEN_FRR_NIRQS flag is used to override the detected value of num_sources with the manual irq_count parameter. Since there's no need to manually specify the number of IRQs except in this case, the extra flag can be eliminated and the test changed to "irq_count != 0".
