[PATCH 03/11] irqchip: bcm7120-l2: Eliminate bad IRQ check

This check may be prone to race conditions, e.g. 1) Some external event (e.g. GPIO level) causes an IRQ to become pending 2) Peripheral asserts the L2 IRQ 3) CPU takes an interrupt 4) The event from #1 goes away 5) bcm7120_l2_intc_irq_handle() reads back a 0 status Unlike the hardware supported b
