Changes since V2:
	-Removed userspace error stats clear debug fs entry as suggested by Adrain Hunter.
	-Split patch into 4 patches
		[PATCH V3 1/4] : sdhci driver
		[PATCH V3 2/4] : debug fs entries
		[PATCH V3 3/4] : core driver
		[PATCH V3 4/4] : cqhci driver
	-Used for loop to print error messages instead of using printf
	 statements for all error messages as suggested by Adrain Hunter.
	-Introduced one flag to enable error stats feature, if any other
	 client wants to use this feature, they need to enable that flag.
	-Moved reset command timeout error statement to card init flow
	 as suggested by Adrain Hunter.

Changes since V1:
	-Removed sysfs entry for eMMC and SD card error statistics and added
	 debugfs entry as suggested by Adrian Hunter and Ulf Hansson.
