ARM: mxs: icoll: Fix interrupts gpio bank 0
The mxs interrupt controller does not support polling for interrupts, but the driver still does it, which is a relict from pre-MULTI_IRQ_HANDLER times. The existing code assumes that 0x7f means no interrupt, but this value is an actually valid irq number, namely gpio bank 0's irq. This results in the driver not detecting when irq 0x7f is active which makes the machine effectively dead lock. This patch removes the interrupt poll loop and allows usage of gpio0 interrupt without an infinite loop.
