stmmac: reorganise class operations.

This patch reorganises the internal stmmac ops structure.
The stmmac_ops has been splitted into other three structures named:
 stmmac_ops
 stmmac_dma_ops
 stmmac_desc_ops

This makes the code more clear and also helps the next work to
make the driver more generic.
