The correct name for aliases node is "aliases" not "alias".

An overview of the "aliases" node usage can be found
on the device tree usage page at devicetree.org [1].

Also please see chapter 3.3 ("Aliases node") of the ePAPR 1.1 [2].

What uses this alias?  If the answer is nothing (likely, as it was 
broken and nobody seems to have noticed), just remove the whole
thing.

I have used ar9132_tl_wr1043nd_v1.dts as a template for AR9331-based
board dts-file. AR9331 uses it's own very special UART implementation
(the ar933x_uart.c driver is used). ar933x_uart.c relies on alias and
does not work if alias is not set. I have not yet runned linux on
TL-WR1034ND, but I suppose that uart alias is not actually used for
TL-WR1034ND and this aliases node can be safely removed.

Alban, have you any comments?

David is right, we should just remove it.
