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.

Looks this property value is incomplete: missing cpu1/2/3/4_intc ?
