[PATCH] imx28-xea: Add missing imx28-lwe.dtsi

From: Fabio Estevam <festevam at denx.de>

The following build error is seen when building imx28_xea_defconfig:

arch/arm/dts/.imx28-xea.dtb.pre.tmp:8:10: fatal error: imx28-lwe.dtsi: No such file or directory

This happens because commit ebcca534f557 ("imx28: synchronise device tree
with linux") missed to import the imx28-lwe.dtsi file from Linux.

Fix it by importing the file from Linux 6.1-rc1.

Fixes: ebcca534f557 ("imx28: synchronise device tree with linux")

This applies against u-boot-imx master-next branch.
