Users can configure the runtime supported HW configurations of a physical
link by SectionHWConfig. A physical link can refer multiple HW config
sections in SectionLink.

Users may not use DPCM but still need to configure the physical links.
So we should not only consider backend links for DPCM.
- SND_TPLG_TYPE_LINK is defined to configure physical links by C API.
And SND_TPLG_TYPE_BE is still supported to configure Backend links for
DPCM cases.
- SectionLink can be used to configure physical links in text conf file.
And SectionBE is still supported to config Backend links for DPCM cases.
Actually, users can use SND_TPLG_TYPE_LINK and SectionLink to configure
backend links for DPCM cases, because BE links are also physical links.
The parsing is same and we rename the function from tplg_parse_be to
tplg_parse_link.

Code refactoring. When adding a physical link element from C API:
- Rename "link" to "link_tpl" for physical link config template for
C API users.
- Rename "lk" to "link" for physical link elements created by topology
internally.

Code refactoring. Rename the function to build all physical links from
tplg_build_link_config() to tplg_build_links(). And define a new function
build_link() to build a single physical DAI link element.
The function build_link() will be extended to handle more properties
of a physical DAI link (e.g. backend or codec-codec link).

Code refactoring. Previously an element has two pointers, 'be' and 'cc',
for BE (Back End) and CC (Codec-Codec) link respectively. But actually
the topology tool processes BE and CC links in the same way, so these
two pointers can be merged into one 'link' pointer, which can be used
configure any physical links.

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.

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.
