[v2,6/9] riscv: sifive: dts: fu540: Add board -u-boot.dtsi files

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.
