The reason I removed them was due to the SoC DTSI example shown in [1]
lacking empty lines between properties, but then using them instead as
visual separation between properties and child nodes, or at least that's
how I understood it when I looked at it.

Personally, I prefer the look of the SoC DTSI example - but I don't mind
recreating the patch set with the empty lines between the properties 
left
entact.

As there is a mix of property spacing and ordering styles in mt7621.dtsi
already - what is the consensus on what a node in this file should look
like?

I also don't mind following that pattern and cleaning up the whole dtsi
according to that if it'll save us all time and energy in future.
