Move the aliases to the .dts files and drop the ones that are disabled.

make this

What's wrong with the other IRQs? Not connected?

Almost all devices are in the 0xfd000000 range. Could this be a bus in the
SoC that has all the devices attached to it? Maybe use a "ranges" property
to reflect that. In doubt, use the register numbers from the data sheet if you
have one.
