REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2218 Stopping the SD clock before switching host controller bus timing is only necessary if preset value enable is set in host controller. Code that performs switch to HS200 doesn't check this condition right now and we also don't do the SD clock stop before any other bus timing switch in host controller. Since the driver is generally not ready to support host controller with preset value enable set we removed this code.
