deac7fc1c8 irqchip/gic-v3-its: Parse new version of msi-parent property 
Now that 126b16e2ad ("Docs: dt: add generic MSI bindings")
has made it into the tree, the time has come to get rid of the
old hack, and to parse msi-parent in its full glory.

be5436c83a irqdomain/msi: Use fwnode instead of of_node 
As we continue to push of_node towards the outskirts of irq domains,
let's start tackling the case of msi_create_irq_domain and its little
friends.

This has limited impact in both PCI/MSI, platform MSI, and a few
drivers.

1e6db00048 irqchip/gicv3-its: Add platform MSI support 
In order to support non-PCI MSI with the GICv3 ITS, add the minimal
required entry points for the MSI domain (an msi_prepare implementation).

The rest is only boilerplate code to find the raw ITS domain.
