The newer ibm,drc-info property is a condensed description of the old ibm,drc-* properties (ie. names, types, indexes, and power-domains). When matching a drc-index to a drc-name we need to verify that the index is within the start and last drc-index range and map it to a drc-name using the drc-name-prefix and logical index. Fix the mapping by checking that the index is within the range of the current drc-info entry, and build the name form the drc-name-prefix and by adding the starting drc-name-suffix value with the sequential index of subtracting ibm,my-drc-index from this entries drc-start-index.
