ASoC: SOF: hda: set autosuspend delay for hda bus device

ranj063 · ranj063 · commit 9944ebbd9d27 · 2019-05-23T23:57:49.000-07:00
Set the autosuspend delay for hda bus device. This prevents
the hda codec device from entering runtime suspend
when running stress tests involving opening/closing
streams one after the other.
