mmc: omap_hsmmc: add support for pre_req and post_req
pre_req() runs dma_map_sg(), post_req() runs dma_unmap_sg. If not calling
pre_req() before omap_hsmmc_request(), dma_map_sg will be issued before
starting the transfer. It is optional to use pre_req(). If issuing
pre_req(), post_req() must be called as well.
