Olof Johansson f8060f5446 Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas
 Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
 and adapted to use the new infrastructure. All DT enabled platforms
 using GIC and VIC are converted over to use the new irqchip_init.

Initial irqchip init infrastructure and GIC and VIC clean-ups

This creates irqchip initialization infrastructure from Thomas
Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
and adapted to use the new infrastructure. All DT enabled platforms
using GIC and VIC are converted over to use the new irqchip_init.
