On FSP based machine, attention LED location code is passed to OPAL via HDAT. We want to populate this information in device tree under led node, so that LED driver can use this information. Presently we are creating '/ibm,opal' node after parsing hdata information. This patch validates '/ibm,opal' node before creating. So on FSP based machine we can create this node in hdata itself without breaking.
