sof-dump-status: dump pipeline info from proc for legacy HDA

To reuse test cases from sof-test repo, we need to
dump pipeline info from proc, just like dump pipeline
info from topology on SOF platform.

As there is no format/channel/rate information in proc,
we hard code some default format/channel/rate values,
this should be enough for legacy HDA platform test.
