Previously in text conf file, an element can only refer to one data
section (SectionData). Now it can also refer to a list of data sections.
Thus users can split groups of firmware parameters to multiple data
sections, and put them all in the reference list.
Finally, data of these data sections will be merged, in the same order as
they are in the reference list, as the element's private data for kernel.
We still support the original syntax of reference to a single data
section. The doc is updated for the syntax extension.

Many element types have private data. So use the generic obj pointer
instead of the type-specific pointer when reallocating the object to
accommodate the private data.
Empty private data will be overlooked.

For data objects with tuples, the parser will bind the vendor tuples
and tokens, copy the tuples to the private buffer of its parent data
object. Then later the builder will export the vendor tuples as private
binary data for the control or widgets objects.

Vendor can define several tuple arrays in 'SectionVendorTuples', as
well as the reference to a vendor token list object.
A later patche will copy vendor tuples in ABI format to the private
buffer of its parent data object in the building phase.

Vendor can define a token list in SectionVendorTokens. Each token element
is a pair of string ID and integer value. And both the ID and value are
vendor-specific.

Add support to lookup elements by name. This is in preparation for adding
some new API calls that will allow building topology data using a C API. This
will allow applications to build their own topology data directly.
