Add service file to synchronize INPUT_HISTORY data
During the power on sequence, the power supplies should have their
INPUT_HISTORY data synchronized. This can be accomplished by toggling
the PS_FFS_N GPIO pin low then high. Use existing phosphor-gpio-util
application to accomplish this. This INPUT_HISTORY data will be used
later for telemetry data. Do not toggle on reboot with power on.
