Twinkie: Enable flashing with dfu-util.
Twinkie only has test points for uart connection so nominally it will
need to be programmed via DFU mode over USB micro-B connection.
This CL changes from programming via flash_stm32 function and instead
adds dfu support.
BUG=chrome-os-partner:28337
TEST=util/flash_ec --board=twinkie successfully programs twinkie f/w
