topology: pre-process-obejct: add helper function to get the section config

Browse source 
Add a helper function to retrieve the config node
pointing to the section name for a given object.
For ex: for the object, Object.Widget.pga.1{},
the function returns the config with id, "SectionWidget"
in the output config.
