[RFC PATCH 05/14] 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.
