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.
