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 from 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.
