One can pass either a board name (e.g. hammer) or a chip name (stm32)
to the flash_ec command. If given a board name, will map to a proper
chip name and then call its chip-flashing method.
The NEED_SERVO variable ("no" if servo not needed) was set according
to the board name. It was broken if only given a chip name. It should
be set according to the chip name.
