Adding function type checking to IRQCHIP_OF_DECLARE found a type mismatch
with icoll_of_init. The function should return an error code or 0 on
success.

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.

Move icoll.c into drivers/irqchip as irq-mxs.c, and along with the
renaming, change the driver to use IRQCHIP_DECLARE.
