ASoC: SOF: Intel: hda: use hdac_ext fine-grained link management
Opt-in to use snd_hdac_ext_bus_link_power() to manage HDA link power up/down events. This allows to reduce power consumption in cases where some HDA codecs are suspended, but other child devices (HDA or non-HDA codecs) remain active and controller itself remains in active state. By using snd_hdac_ext_bus_link_power(), the individual HDA links can be powered off and if all HDA codecs are powered down, the command DMA can also be shut down.
