Some OEM will integrate fingerprint device with powerButton. It's
possible that a user may press the power button during fingerprint
enroll or identify. This would lead to unintended PC shutdown or
hibernation. We add pwr_btn_shield cmd  and related process to shield
the power button function when the fingerprint functionality (enroll and
identify) is used and restore power button function afterwards.
