The HDA links can be switched off when not is use, similarly command DMA can be stopped as well. This calls for a reference counting mechanism on the link by it's users to manage the link power. The DMA can be turned off when all links are off
For this we add two APIs snd_hdac_ext_bus_link_get snd_hdac_ext_bus_link_put
They help users to turn up/down link and manage the DMA as well
