Current ASoC overwides dai->driver->ops if it was NULL. But, it is not good idea, because dai->driver might be reused when modprobe/rmmod or bind/unbind, etc.
This patch checks dai->driver->ops when use DAI callbacks, and removes null_dai_ops from ASoC.
This is fine but it's not a correctness issue since we're always filling the same value in - the big issue with putting stuff in structures is when you end up using the same struct for two different different things so you fill different values in.
