Bill Richardson bb15561db5 cleanup: DECLARE_CONSOLE_COMMAND only needs 4 args
Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.

We're never going to use this, let's just get rid of it.

BUG=none
BRANCH=none
CQ-DEPEND=CL:*279060
CQ-DEPEND=CL:*279158
CQ-DEPEND=CL:*279037
TEST=make buildall; tested on Cr50 hardware

Everything builds. Since we never used this arg anyway, there had
better not be any difference in the result.
