[platform-device/haliburton] Support xcvr and sensor monitoring (#1998)

* [platform/haliburton] Fix kernel panic when remove smc module.

* [platform/haliburton] Chanage sysfs to support module interrupt

* [device/haliburton] Update sfputil to use new sysfs.

* [device/haliburton] sfputil to support xcvrd monitoring.
