Tara Subedi 37a21a504c No ptp alarm is raised when ts2phc is stopped

When ts2phc is configured without ts2phc.nmea_serialport, in case
of "-s generic", alarm configuration was not created, and this is
not raising alarm when the ts2phc service is down.

This commit fixes by having ts2phc alarm configuration even when
there is no ts2phc.nmea_serialport.

TEST PLAN:
PASS: Configure ts2phc without nmea_serialport, stopping ts2phc
        shows alarm.
      system ptp-instance-add ts1 ts2phc
      system ptp-instance-parameter-add ts1 cmdline_opts='-s generic'
      system ptp-interface-add tsint1 ts1
      system host-if-ptp-assign controller-0 oam0 tsint1
      system host-ptp-instance-assign controller-0 ts1
      system ptp-instance-apply

      stop ts2phc: sudo systemctl stop ts2phc@ts1.service
      'fm alarm-list' shows: controller-0 PTP service
        ts2phc@ts1.service enabled but not running

      start ts2phc, alarm get cleared.
      There are no other errors on collectd.log

PASS: Configure ts2phc with non-existing device on nmea_serialport,
      stopping ts2phc shows alarm.
      system ptp-instance-parameter-delete ts1 cmdline_opts='-s generic'
      system ptp-instance-parameter-add ts1 cmdline_opts='-s nmea'
      system ptp-instance-parameter-add ts1 ts2phc.nmea_serialport=/dev/gnssx
      system ptp-instance-apply

      'fm alarm-list' shows no alarms
       stop ts2phc: sudo systemctl stop ts2phc@ts1.service
       'fm alarm-list' shows 'controller-0 PTP service ts2phc@ts1.service
          enabled but not running'
       There are no other errors on collectd.log

PASS: Configure ts2phc with existing device on nmea_serialport, to see working
        as usual.
      stopping ts2phc shows alarm.
      system ptp-instance-parameter-delete ts1 ts2phc.nmea_serialport=/dev/gnssx
      system ptp-instance-parameter-add ts1 ts2phc.nmea_serialport=/dev/gnss0
      system ptp-instance-apply

      'fm alarm-list' shows no alarms
       stop ts2phc: sudo systemctl stop ts2phc@ts1.service
       'fm alarm-list' shows 'controller-0 PTP service ts2phc@ts1.service
          enabled but not running'
       There are no other errors on collectd.log

PASS: Other instances (ptp4l, phc2sys) are working normally
