In cases when only one type of device (PSS or EEC) is connected, the ptp
notification app stay stuck in FAILURE-NOFIX even when the disconnected
device change to connected status.
To solve this, the pins structure is cleaned when only one device is
connected (PSS or EEC) forcing a new pin read on the next validation.
TEST PLAN:
PASS: Status change to FAILURE_NOFIX in case of disconnected pin
PASS: Status change to LOCK_HO_ACQ in case of connected pins in EEC and
PPS devices
