[PATCH] rockchip: rk3588-nanopc-t6-lts: Add missing board -u-boot.dtsi

[Jonas Karlman]

The commit 7cec3e701940 ("rockchip: rk3588-nanopc-t6: Add support for
NanoPC-T6 LTS") added support for the LTS variant of NanoPC T6. However,
a board specific -u-boot.dtsi file was never added.

Due to the missing -u-boot.dtsi file the LTS fdt included in the FIT is
never tagged with bootph props.

When ENV_IS_IN_SPI_FLASH is enabled, not enabled in defconfig, the env
can successfully load from SPI flash on the non-LTS variant, something
that does not work on the LTS variant due to missing bootph-some-ram
props in the LTS fdt.

Fix this by adding a LTS -u-boot.dtsi file that just include the non-LTS
-u-boot.dtsi file.
