mailbox: mtk-cmdq: Switch to pm_runtime_put_autosuspend()

[ Upstream commit 472f8a3 ]

__pm_runtime_put_autosuspend() was meant to be used by callers that needed
to put the Runtime PM usage_count without marking the device's last busy
timestamp. It was however seen that the Runtime PM autosuspend related
functions should include that call. Thus switch the driver to
use pm_runtime_put_autosuspend().
