[PATCH v2 17/21] binman: doc: Add documentation to htmldocs

[Simon Glass]

Add a link to binman's documentation and adjust the files so that it is
accessible. Use the name README.rst so it is easy to discover when binman
is installed without U-Boot.

Changes in v2:
- Put binman docs in doc/develop and FIT in doc/usage
- Rename README.rst to binman.rst and use a symlink
