Added a PCD to turn on/off probing Block IO devices to detect add/remove/change. FAT driver does not do this so if the shell does not do this you will get dir hits on an SD Card that has been removed. Default is ON. I moved this feature from device command to main command loop so it gets done after you type return before your command is processed.
