Using private mapping is not recommended.
Maybe we can do it together with this patch since irqdomain support
does not depend on device tree.
What do you think?

At this point, I would be conservative on that, since I do not have
the setup to test all the IPU irq handling.

I looked into the code a bit more, it seems ipu uses its own special irq mapping
between virt irq and hw/dma_chan irq itself and the mapping is dynamically
and limited to how many CONFIG_MX3_IPU_IRQS defined.
No sure it's so suitable to convert to irqdomain.
With adding irqdomain, i wonder we may need change this mechanism a bit.

For now, i'm ok to put that work in another patch later and using the original
way first since the later patch may need to do more things, so
