meta-openpower: Add pdata support

OpenPOWER systems uses devicetree based data structure
to manage CEC hardware information. Devicetree data
modelling mainly includes the hardware topology and attributes,
which includes the configuration data.

Devicetree data base is constructed during the build time,
based on the System specific MRW and hardware team provided
attributes, and packaged as part of Hostboot image.

pdata provides tools and libraries to manage the
phal(power hardware abstraction layer) devicetree.
