Allow TMIO and SDHI driver implementations to provide values for
max_segs and max_blk_count.
A follow-up patch will set these values for Renesas Gen3 SoCs
the using an SDHI driver.

Make renesas_sdhi_sys_dmac.c a top-level module file that makes use of
library code supplied by renesas_sdhi_core.c
This is in order to facilitate adding other variants of SDHI;
in particular SDHI using different DMA controllers.

Rename the source file for DMA for SDHI as a follow-up to attaching
DMA code to the SDHI driver rather than the tmio_core driver.
The name "renesas" is chosen as the SDHI driver is applicable to a wider
range of SoCs than SH-Mobile it seems to be a more appropriate name.
However, the SDHI driver source itself, is left as sh_mobile_sdhi to
avoid unnecessary churn.
The name sys_dmac was chosen to reflect the type of DMA used.
Internal symbols have also been renamed to reflect the filename change.
A follow-up patch will re-organise the SDHI driver removing
the need for renesas_sdhi_get_dma_ops().
