servo_micro: move ite flashing code
In preparation for servo_micro and c2d2 to sharing the ite, i2c flashing
code, move it to a stm specify common file. It is STM specific because
it explicitly uses STM registers to accomplish the non-compliant i2c
waveforms needed to put the ITE EC into flash mode.
BRANCH=servo
BUG=b:148610186,b:79684405
TEST=flash ampton with servo_micro using this code
