Try to be cossistent in capitilization of Dpu versus DPU

Bindings should use an indent of two spaces.
This is what is used in the example schema and the de-facto standard.
One space indent makes it very hard to follow the indent.

For examples the indent varies. From 2 spaces to 8 spaces.
I often use 4 spaces as 2 spaces is not enough when it spans several
lines. But there is nothing fixed there.

Add empty line between properties (empty line before reg:).

Should this be power-domain.yaml?

Do not use "|" unless required. Fine to have text on same line as
description: .
