powerpc/lib/sstep: Fix building for powerpcspe

On powerpcspe, ptesync is not a recognised instruction and so fails to
assemble. We don't expect to have to emulate an lwsync or a ptesync on a
32-bit kernel, so just ifdef them out, and catch any unexpected barrier
types.

Fixes: 3cdfcbfd32b9 ("powerpc: Change analyse_instr so it doesn't modify *regs")
