ARM i.MX avic: convert to use generic irq chip
Convert i.MX avic irq handler to use generic irq chip. This not only
provides a cleanup implementation of irq chip handler, but also
implements suspend/resume interface with the help of generic irq chip
interface.
Change mxc_irq_chip to a new structure mxc_extra_irq to handle fiq
and priority functions.
