This patch adds the SDHCI support for APM X-Gene SoC using ARASAN SDHCI
controller.
v1 change:
* Use the CONFIG_ARM64_DMA_HAS_IOMMU for dma-mapping.
v2 change:
* Drop the IOMMU support and switching to PIO mode for arasan
controller integrated inside APM X-Gene SoC.

Use of block layer runtime PM helpers, implementing the block layer's
request-based mechanism, simplifies data path of mmc core layer. It
enables to remove synchronous call pm_runtime_get_sync() from mmc core
data path.
The idea and API is designed by Alan Stern and described here:

MMCIF IP on R-Car series has parent clock which can be set
several rate, and it was not implemented on old SH-Mobile series
(= SH-Mobile series parent clock was fixed rate)
R-Car series MMCIF can use more high speed access if it setup
parent clock. This patch adds parent c

Hi Ulf
These patches are v3 of sh_mmcif.
Current sh_mmcif driver was used on Renesas SH-Mobile series,
and it is also used on Renesas R-Car series.
But, R-Car series can setup parent clock.
We couldn't setup it when SH-Mobile.
These patches are tested by Kobayashi-san on Lager board.
