[PATCH 2/3] ARM: dts: UniPhier: add on-chip UART device nodes

From: Masahiro Yamada
Date: Sun Jul 05 2015 - 23:51:12 EST

The UniPhier on-chip UART driver was merged into the mainline by
commit 1a8d2903cb6a (serial: 8250_uniphier: add UniPhier serial
driver).

Add device nodes to make it really available.

We no longer have to depend on the on-board UART device (16550A),
so let's change the chosen and aliases to point to the on-chip ones.
Also, turn on the on-board Ethernet device.
