Please sort such labeled node alphabetically in label name. That said,
it should go after &lpuart0.

I do not see this property in bindings doc.

Please let 'status' line be the last of property list.

Please sort the node in <soc>.dtsi in order of unit-address. That said,
the node should be added between ifc at 1530000 and esdhc at 1560000.
