mmc: mmci_sdmmc: Replace sg_dma_xxx macros
commit 127e6e98 upstream. sg_dma_xxx should be used after a dma_map_sg call has been done to get bus addresses of each of the SG entries and their lengths. But mmci_host_ops validate_data can be called before dma_map_sg. This patch replaces theses macros by sg->offset and sg->length which are always defined.
