Remove the simple-bus compatible from a regulators node because its
children do not have any unit addresses. This fixes DTC warning:

Add @0 unit address to 'soc' node match its 'reg' property and move the
thermal zones out of 'soc' to main root as it this is usually not a
property of a Soc.
This silences DTC warnings:
Warning (unit_address_vs_reg): /soc: node has a reg or ranges property, but no unit name
Warning (simple_bus_reg): /soc/thermal-zones: missing or empty reg/ranges property

I think you would also need to remove the 'regulators' node altogether,
otherwise with your change the subnodes below won't get parsed and the
regulators will not get registered.

Good point, I actually did not test this patch. Let me recheck and send
a follow up.
Thanks for review!
