We can distinguish different use cases by the object index value, the default
value is 0, meaning applicable for all use cases, defined by macro "SND_TOLG_INDEX_ALL".
An element can only refer to other elements for "all" use cases or the same use
cases, i.e. it can only refer to elements with index value "SND_TOLG_INDEX_ALL"
or the same index value as itself.
The object list has been sorted in ascending order of index, so when we look up
a reference for an object, we traverse the object list it depends on, if we have
not found the reference until index of the object list is greater than index of
the object, we give up and return an error.

We insert a new element into the object list based on its index value, so we parse
index value in "tplg_elem_new_common" before insert it, and then remove code
parsing index value in parsing each object.

The topology source files had the wrong licence specified in the
comments when initially upstreamed. The topology source files are all
licensed under the LGPL-2.1 and not the GPLv2.
All earlier versions of the alsa-lib topology source files must be
considered LGPL-2.1 like the other source files in alsa-lib and also
as specified in the alsa-lib COPYING file.

Enum controls may use text elements and need the number of strings.
This patch adds a text child object for a generic element. When parsing
a text section from the configuation file, store the text strings and
number of strings (num_items) in the text child object of the element.

This access flag is used to add controls from user space by ioctl.
But topology only configures controls in user space and these controls
will eventually be created by ASoC in kernel, so topology should not
support this flag.

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.

Currently the TLV topology structure is targeted at only supporting the
DB scale data. This patch extends support for the other TLV types so they
can be easily added at a later stage.
TLV structure is moved to common topology control header since it's a
common field for controls and can be processed in a general way.
Users must set a proper access flag for a control since it's used to decide
if the TLV field is valid and if a TLV callback is needed.
Removed the following fields from topology TLV struct:
- size/count: type can decide the size.
- numid: not needed to initialize TLV for kcontrol.
- data: replaced by the type specific struct.
Added TLV structure to generic control header and removed TLV structure from
mixer control.
