For nearly all commands in U-Boot the '?' variable is handled the same
way with 0 meaning success, 1 meaning any failure. Explain this in the
general rules section of the cmdline documentation (with a link to a
counter example) and then remove the redundant wording from most
commands. We retain a section about the return value in a number of
places where we are doing something such as always returning a specific
value or we have useful additional information to go along with the
normal return codes.

Changes in v2:
- Rewordings suggested by Quentin
- After confirming that invalid syntax also always returns 1 and not -1,
For example cmd/scmi.c do_scmi_set_proto() can return CMD_RET_USAGE
which is a -1 enum and the function returns an int, so I assume this
would be propagated properly?
I don't have time today to check the cmd function call stack to see if
it is, but this seems odd to me.
Cheers,
Quentin
