Hi,
this short series adds support for R-Car Gen-3 DMA to the SDHI driver.
The approach taken is as follows:
1. Rename sh_mobile_sdhi.c as renesas_sdhi.c
2. Refactor the TMIO DMA code so that it is provided by a set of callbacks
rather than compiled-in function calls; Refactor the DMA SDHI to use this.
3. Rename tmio_mmc_dma.c as renesas_sdhi_dma.c which reflects more closely
what it is is, particularly after step 2.
4. Add Gen3 DMA code as a separate set of callbacks
Please note that currently the DMA callbacks used are determined based
on the SDHI compat string in effect.
Based on mmc/next
