drivers: dma: intel-adsp-hda: add delay to stop host dma

According to hardware spec, host dma needs some delay to completely stop.
In the bug the host dma is disabled in different path in a few microseonds.
The first setting disabled the host dma and called pm_device_runtime_put
to power off it. The second setting found the host dma was still alive
and calle pm_device_runtime_put again. This results to pm->usage
checking failed.
