I should remove this change because cpu dai should support sysclk ops.

Thank you for this good catch.
Here machine driver has the knowledge of deciding whether it is
expected to see the ops is not supported.
For HDMI path using hdmi-codec driver, it is expected to see -ENOTSUPP.
But it is not expected for codec DAI of max98090.
I should distinguish them.
