ASoC: qcom: sdm845: Disable the quaternary MI2S bit clock on shutdown
sdm845_snd_startup() enables the quaternary MI2S bit clock in the ADSP,
but sdm845_snd_shutdown() never disables it. After the first stream on
this port the clock stays on.
On the OnePlus 6 the speaker amplifier is on this port. After the first
playback the ADSP no longer power collapses: it slept under 9 s in 5
hours. With this change it sleeps again when audio is idle (about 40 s
of 45 s).
Refcount the clock like the other MI2S and TDM ports and disable it
when the last user is gone.
