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 also use SND_TPLG_TYPE_LINK and SectionLink to configure backend links for DPCM cases, because BE links are physical links. So the parsing is same and we rename the function from tplg_parse_be to tplg_parse_link.
