Subject: [PATCH] ARM: dts: rockchip: Move uart aliases to SoC dtsi for RK3128

SoC TRM, SoC datasheet and board schematics always refer to the
same uart numbers - even if not all are used for a specific board.
In order to not have to re-define them for every board move the
aliases to SoC dtsi for RK3128 like it's being done for all other
Rockchip ARM SoCs.
