ARM: vic: MULTI_IRQ_HANDLER handler
Add a handler for the VIC that is suitable for MULTI_IRQ_HANDLER
platforms. This can replace the ASM entry macros for platforms that use
the VIC.
v4: - rebase ontop of move __exception and friends to
asm/exception.h
- rework polling loop to handle as many irqs as possible in one go
v3: - simplify irq handling loop as suggested by Grant
- service interrupts from msb->lsb order
v2: - allow the handler be used for !CONFIG_OF
- use irq_domain_to_irq()
