The UARTs on the A20 can be muxed to several pins. Add a few options to
the DTSI so that we can start using them in the boards' DT.

Why have address part of the node name if there's not "reg" property?
And the preferred node name is "serial", not "uart", according to the ePAPR
spec (http://www.power.org/resources/downloads/Power_ePAPR_APPROVED_v1.0.pdf).
