Rahul Pathak	d98da90a19	lib: sbi_illegal_insn: Fix FENCE.TSO emulation infinite trap loop ... In case of missing "FENCE.TSO" instruction implementation, opensbi can emulate the "FENCE.TSO" with "FENCE RW,RW", but mepc was not incremented to continue from the next instruction causing infinite trap.

Samuel Holland	39d1e698c9	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`.
