[Skiboot] [PATCH 1/3] hw/occ: Fix psr cpu-to-gpu sensors node dtc warning.

[Pridhiviraj Paidipeddi]

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

/ibm,opal/power-mgt/psr/cpu-to-gpu at 0 has a unit name, but no reg property
/ibm,opal/power-mgt/psr/cpu-to-gpu at 100 has a unit name, but no reg property

This patch fixes this by adding necessary properties.
