This patch can create multiple enumerated mixer controls for a widget.

Previously topology kernel driver assumes a widget can have only one
emumerated mixer control. We need to remove this restriction for Broxton.
Its firmware modules (widgets) may need multiple enum controls based on
the channel and MIC combination.

No ABI change is needed. The ABI allows a widget to embed multiple
controls.

Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.

This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
  find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.

This patch adds support for old version 4 of PCMs (FE DAI & DAI links).

Topology ABI v5 added new fields to stream caps and thus changed PCMs.
Since user space may still uses v4, kernel will check the ABI version by
comparing the object size. If user space uses v4 of PCMs, kernel will
create the latest version of PCMs from the old version, and use the new
version internally to create FE DAI & DAI links. Because these new created
PCM elements will be freed later, kernel need duplicate the name strings
of DAI driver and DAI links when creating them.

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.

The topology core parses the FW topology file for known block types and
instanciates any common ALSA/ASoC objects that it discovers. The core
also passes any block that is does not understand to client component
drivers for enumeration.

The core exports some APIs to client drivers in order to load and unload
firmware topology data as use case require.

Currently the core deals with the following object types :-

 o kcontrols. This includes TLV, enumerated and bytes controls.
 o DAPM widgets. All types with any associated kcontrol.
 o DAPM graph.
 o FE PCM. FE PCM capabilities and configuration can be defined.
 o BE DAI Link. BE DAI link capabilities and configuration can be defined.
 o Codec <-> codec style links capabilities and configuration.
