This patch reads card detect properties from device tree & added mmc capability macros in mmc.h.
Signed-off-by: T Karthik Reddy t.karthik.reddy@xilinx.com Signed-off-by: Michal Simek michal.simek@xilinx.com ---
Changes in v3: - Changed MMC_CAP_SD_NONREMOVABLE, MMC_CAP_SD_NEEDS_POLL names to align with Linux bit definitions by removing SD.
Changes in v2: - Moved reading CD devicetree properties functionality from sdhci.c to mmc-uclass.c & moved mmc capability macros to mmc.h from sdhci.h.
