servo_micro: Add enable_ite_dfu and get_ite_chipid console commands.
enable_ite_dfu: Enable direct firmware update (DFU) over I2C mode on
ITE IT8320 EC chip by sending special non-I2C waveforms over the
I2C bus wires.
get_ite_chipid: Verify that DFU mode is enabled by querying the EC over I2C
for its CHIPID1 and CHIPID2 registers. It will only respond over I2C when
in DFU mode.
BRANCH=none
BUG=b:79684405
TEST=get_ite_chipid succeeds after enable_ite_dfu
