There are cases where a pointer function populates
runtime->delay, such as:
./sound/pci/hda/hda_controller.c
./sound/soc/intel/atom/sst-mfld-platform-pcm.c
Also, in some cases cpu dai used is generic and the pcm
driver needs to set delay.
This delay was getting lost and was overwritten by delays
from codec or cpu dai delay function if exposed.
