Marc Zyngier 1f83515beb genirq/msi: Allow creation of a tree-based irqdomain for platform-msi ...

platform_msi_create_device_domain() always creates a revmap-based
irqdomain, which has the drawback of requiring the number of MSIs
that can be allocated ahead of time. This is not always possible,
and we sometimes need to use a tree-based irqdomain instead.

Add a new platform_msi_create_device_tree_domain() helper to
that effect.
