irq_domain/c6x: Convert c6x to use generic irq_domain support.
The C6X IRQ support was copied almost verbatim from the PowerPC virtual IRQ code. The PowerPC code was used as the basis for generic irq_domain support, so this patch mostly copies what what done to arch/powerpc by Grant Likely in his irq_domain patch series.
