servo_micro: add usart cmd to hold pins low
To enabled UART (UUT) programming mode for some ECs, we need to
drive the EC_TX_SERVO_RX line low while the EC is rebooting.
Add a console command that is controllable by dut-control that will
drive the UART pins low while the UART is disabled, until the command to
re-enable the UART is sent on the console.
Also, remove unnecessary alternate mode initialization for USART4
(UART3).
