flash_ec: add support for closed-case debugging
Passing the "--usb" argument will now utilized case-closed
debugging for flashing the EC. Currently this is only supported
for the samus LM4-based board.
BRANCH=none
BUG=none
TEST=verify that when the case-closed debugging flag is set, the
alternate openocd config file is used for samus, and an error is
thrown for all other boards
