Underscores must not appear in node names, use hyphens instead

Also, nodes without a reg property / unit address don't belong under
the /soc node.

It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

Please read carefully DTS coding style and follow it in your DTS
submissions.

Best regards,
Krzysztof
