Sync the hifive-unleashed-a00 dts from Linux with
below commit details:
commit 11ae2d892139a1086f257188d457ddcb71ab5257

riscv: dts: fu540-c000: drop "timebase-frequency"
Idea is to periodically sync the dts from Linux instead of
tweeking internal changes one after another, so better not
add any intermediate changes in between. This would help to
maintain the dts files easy and meaningful since we are
reusing devicetree files from Linux.
