The Cheza EC requires EC_RX_H1_TX be held low while the EC is being reset to enter gang mode. This change adds another programming mode to ec usb spi programming to do that. BUG=b:74388083 BRANCH=cr50 TEST=The cheza boards aren't in, so I just tested EC_TX_CR50_RX_OUT gpioset EC_TX_OUT 0 and 1 setup EC_TX_CR50_RX_OUT correctly as an output when asserted and an input when deasserted.
