ASoC: Intel: Skylake: enable interrupt as wake source in active suspend

In active suspend, any HDA interrupt should wake the system. When device
enters active suspend, we need to enable HDA controller interrupt as wake
source. Similarly disable HDA controller interrupt as wake source when
exiting active suspend.
