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.

v2:     - allow the handler be used for !CONFIG_OF
       - use irq_domain_to_irq()

__exception_irq_entry doesn't compile with CONFIG_FUNCTION_GRAPH_TRACER enabled.
Either this file, or arch/arm/include/asm/system.h needs an #include
<linux/ftrace.h>
