Hi,

Here is the 2nd version of improving DFU subsystem series. 
This improves dfu_alt_info parser and fixing documents etc.
In this version I fixed a build error of cmd/dfu.c so that
it can be build without DFU_OVER_USB and DFU_OVER_TFTP
(in this case, the platform will use the DFU only for EFI
 capsule update.)

When I was debuging my patch for updating dfu_alt_info on the
DeveloperBox platform, I found that dfu_alt_info parser didn't
accept redundant spaces and tabs. Also the dfu.rst description
seems wrong. Moreover, there is no way to check whether the
parser parses the dfu_alt_info correctly.

These patches fixes such issues. [1/5] is just for avoiding
buffer overrun, [2/5] and [3/5] improves dfu_alt_info parser
to accept redundant spaces and tabs, and check the number of
arguments strictly so that the parser (and user) can notice
any unexpected parameters. [4/5] fixes the documents (there
seems some wrong description maybe coming from copy&paste).
[5/5] allows user to run 'dfu list' even if the platform
doesn't support DFU_OVER_USB nor DFU_OVER_TFTP.

Thank you,
