sensors: Fix dtc warning for new occ inband sensors.

dtc complains about missing reg property when a DT node is having a
unit name or address but no reg property.

/ibm,opal/sensors/vrm-in@c00004 has a unit name, but no reg property
/ibm,opal/sensors/gpu-in@c0001f has a unit name, but no reg property
/ibm,opal/sensor-groups/occ-js@1c00040 has a unit name, but no reg property

This patch fixes these warnings for new occ inband sensors and also for
sensor-groups by adding necessary properties.
