Add a few more error messages to the EC console
Add a few more error messages to the EC console

This adds explanations for all the error codes in enum ec_error_list, so
that console commands that fail can print the reason.

BUG=none
BRANCH=ToT
TEST=none

I can't find any console commands that return errors without explanations,
but I'm planning to add some. This is just preparation.
