Users can define private for PCM (FE DAI & DAI links) elements by both
text conf file and C API:
- Text conf file may define multiple data blocks for a PCM and they will
be merged in building phase;
- Add private data to C API template of PCM object.

Code refactoring. Rename tplg_build_pcm() to tplg_build_pcms() to build
all PCM (FE DAI & DAI link) elements. It will call a new function
build_pcm() to build a single PCM elemement.
build_pcm() will be extended to handle more properties of a PCM.

This commit adds ATTRIBUTE_UNUSED to the unused parameter 'tplg' for
function tplg_parse_streams() and tplg_parse_fe_dai(). These two functions
need to keep 'tplg' as ops for tplg_parse_compound().
The compiler warnings below are fixed:
pcm.c: In function 'tplg_parse_streams':
pcm.c:262:43: warning: unused parameter 'tplg' [-Wunused-parameter]
static int tplg_parse_streams(snd_tplg_t *tplg, snd_config_t *cfg,

pcm.c: In function 'tplg_parse_fe_dai':
pcm.c:324:42: warning: unused parameter 'tplg' [-Wunused-parameter]

Previously these functions are only used by pcm elements (front-end DAI
& DAI link) to parse stream capablities. Now refactor them to be reused
by back-end DAI elements later.

The iterator 'i' in a loop is a usually a integer. But ABI variables use
type _le32, which is converted to host unsigned integer. Comparing them
can cause gcc warning: comparison between signed and unsigned integer

The struct snd_soc_tplg_pcm_dai is renamed to snd_soc_tplg_pcm.
This struct will now be used to handle data related to PCMs
(FE DAI & DAI links). It's not for BE, because BE DAI mappings will be
provided by ACPI/FDT data.
Remove the unused struct snd_soc_tplg_pcm_cfg_caps. We are using
snd_soc_tplg_stream and snd_soc_stream_caps instead.
Define the topology type for BE DAI link: SND_SOC_TPLG_TYPE_BACKEND_LINK.
Define struct snd_soc_tplg_link_config to configure BE & CC links.
Bump ABI version to 4.
