[PATCH v2 0/9] Add SD host controller support for SC9860 platform

[Baolin Wang]

This patch set adds optional clock support, HS400 enhanced strobe mode support,
PHY DLL configuration and other optimization to make the SD host controller
can work well on the Spreadtrum SC9860 platform.

Changes from v1:
 - Add acked-tags from Adrian.
 - Fix one mistake by changing MMC_TIMING_MMC_HS to MMC_TIMING_SD_HS in patch 8.
