[PATCHv1 1/3] arm: mvebu: add uartX labels for Armada SoC serial nodes

[Arnaud Ebalard]

This patch adds uartX labels for Armada SoC serial nodes. This is
a preliminary work to be able to easily reference the serial lines
in Device Tree files. One expected future use is when providing
stdout-path property for barebox.
