This will allow the eventual removal of device_type = "soc"
properties in soc nodes.

Stupid question, but why not remove immrbase instead?

It seems that all users can be converted to use a reg
property of some actual device instead of making assumptions
about the register layout of the whole SOC.

That wouldn't eliminate the need for the alias, though -- u-boot needs 
to find the node to fill in properties.
