Now, we don't need to use dpcm_playback/capture flags for DPCM since v6.11,
and thus we can use playback/capture_only flags instead too for DPCM,
which is same as non-DPCM.
Let's remove dpcm_playback/capture flags, and use playback/capture_only flags
instead.
[Before] [After]
dpcm_playback = 1; /* no setting is needed */
dpcm_capture = 1;
dpcm_playback = 1; playback_only = 1;
dpcm_capture = 0;
dpcm_playback = 0; capture_only = 1;
dpcm_capture = 1;
And then, because no-one uses dpcm_xxx flags, we don't need to have the code
for both DPCM and non-DPCM. These can be handled by same code.
