misc: fs-loader: Use fw_storage_interface instead of storage_interface
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. This is to keep all variables used by fs-loader driver with
'fw_' prefix. All other variables have 'fw_' prefix except for
storage_interface.
The env storage_interface will act as fallback so that the
existing implementations do not break.
Also update the FS Loader documentation accordingly.
