NOP is already handled via instruction emulation and does not require
single-stepping. Drop it from aarch64_insn_is_steppable_hint().

The intent is that aarch64_insn_is_steppable_hint() says whether an
instruction is safe to step, not whether it *must* be stepped. I think
we can leave NOP here unless this is causing some functional problem?
Mark.
