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.

It is useful to obtain the results of cpuid queries, so add a command
for this.
