PHAL: add phal-export-devtree app

d-bus signal based watch app for software path interface add.

This implements methods for watching for software path
interface add signal and call appropriate function to
initiate phal devtree attribute data collection and save
to preserve partition.
Rules:
  - Watch for interfaces added for the software path
  - If interface added is “Activation”
  - if Activation property value is “Ready”
  - Then software update is going to start
  - Collect phal devtree required attribute list and
    save to pre-defined location

This commit enables the d-bus app only.

Tested : verified manually the signals by forcing
         code update.
