[PATCH 3/4] armv8: ls1028aqds: add lpuart dts support

[andy.tang at nxp.com]

From: Yuantian Tang <andy.tang at nxp.com>

Rename fsl-ls1028a-qds.dts to fsl-ls1028a-qds.dtsi so that
it can be used as common device tree for lpuart and duart.
Add lpuart device tree and duart device tree respectively
for qds which are used with duart and lpuart console.
