touch:fts: add PI when config version is same as incoming firmware
If the config config version is same as incoming firmware, the panel is
not calibrated in factory. Driver will do PI when this condition happens.
Bug: 151900042
Test: Panel is calibrated with PI when config version is same with
incoming firmware.
