Many node labels in the device tree (like serial0, serial1, etc) are being
redefined, so let's modernize the device tree by using phandles to
extend the existing nodes.  This helps reduce the whitespace.

V2: Rename subject per feedback from Sekhar.
    Extend notes from tps6507x
    Add empty line after each node

Can you please resend this so it applies to v4.18/dt branch of my tree?
Also, the subject prefix should be "ARM: dts: ".

Thanks,
