[PATCH v2 5/5] cmd/dfu: Enable 'dfu list' command without DFU_OVER_USB

[Masami Hiramatsu]

Since dfu is not only used for USB, and some platform only
supports DFU_OVER_TFTP or EFI capsule update, dfu_alt_info
is defined on such platforms too.

For such platform, 'dfu list' command is useful to check
how the current dfu_alt_info setting is parsed.

 Changes in v2:
   Fix a compile error if CONFIG_DFU_OVER_USB=n && CONFIG_DFU_OVER_TFTP=n.
