The fs-loader driver reads env storage_interface and uses it to load firmware file into memory using the medium set by env. Update the driver to use env fw_storage_interface as this variable is only used to load firmwares. The env storage_interface will act as fallback so that the existing implementations do not break. Also update the FS Loader documentation accordingly.
