[Skiboot] [PATCH 05/12] hdata: Create LED node

[Vasant Hegde]

Unfortunately we do not have single place to get all LED related
information (Some of the information is passed via HDAT and rest
via MBOX command).

Lets create led node before parsing HDAT and use this node to
populate all LED related information.
