This patch reverts the following commits:
- 4b4159d0f3 ("riscv: dts: add dts for unmatched rev1")
- ffe9a394df ("board: sifive: support spl multi-dtb on unmatched board")
We won't plan to support unmatched that the revision below 3 in u-boot,
so they can be dropped because they might be useless.
Changed in v2:
- rebase codebase to the latest master branch
