Devicetree files in FU540 platform is synced from Linux, like other platforms does. Apart from these u-boot in FU540 would also require some u-boot specific node like clint.
So, create board specific -u-boot.dtsi files. This would help of maintain u-boot specific changes separately without touching Linux dts(i) files which indeed easy for syncing from Linux between releases.
