target/ppc: Make divw[u] handler method decodetree compatible.
The handler methods for divw[u] instructions internally use Rc(ctx->opcode), for extraction of Rc field of instructions, which poses a problem if we move the above said instructions to decodetree, as the ctx->opcode field is not popluated in decodetree. Hence, making it decodetree compatible, so that the mentioned insns can be safely move to decodetree specs.
