Samuel Holland cb8271c8e4 lib: sbi_illegal_insn: Add emulation for fence.tso ...

While OpenC906 appears to properly decode `fence.tso` as a fence
instruction[1], the version of the C906 taped out in the Allwinner D1
does not, and raises illegal instruction.

Handle this errata by emulating `fence.tso` as `fence rw, rw`.
