ARM: dts: UniPhier: add on-chip UART device nodes
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.
