hdata: Fix reserved node label search

Soon hostboot/HDAT will provide consistent reserved node name. It will
just provide node name without starting string "ibm,". Commit 50d508c
made sure that all device tree nodes starts with "ibm,".

But we use hostboot/HDAT provided name for `ibm,prd-label` property. So we
have to fix couple of our `ibm,prd-label` property based search/comparision
to accommodate this change.
