Meru800bia: adds P2 devices and sensors to PM/sensor_service

[adamcalabrigo]

Summary

Adds two devices (new to P2) to platform_manager.json then updates sensor_service.json to track the new sensors.

Testing

Verified on Meru800bia.

Started platform_manager, which succeeds and creates the correct new symlinks. From the service log:

Creating symlink from /run/devmap/sensors/SMB_MAX6581 to /sys/bus/i2c/devices/12-004d/hwmon/hwmon8. DevicePath: /SMB_SLOT@0/[SMB_MAX6581]
Creating symlink from /run/devmap/sensors/SMB_MGMT_TMP75 to /sys/bus/i2c/devices/20-0048/hwmon/hwmon14. DevicePath: /SMB_SLOT@0/[SMB_MGMT_TMP75]

Started sensor_service and verified that the new devices are being polled and are correctly reading sensors. From the service log:

Also verified on P1:

PM will log failure in setting up P2 devices:
