High audio volume causes clipping on h3ulcb-refhw

Fixed

Description

During regular tests for master and Koi 11.0.1 on h3ulcb-refhw the default audio volume seems to be too high causing clipping and distortion in the output. 

Lowering the volume makes the audio play properly again.

Audio on standalone m3ulcb or h3ulcb+kf is not affected.

The commits were merged in gerrit last week, sound does not clip anymore on refhw and is working fine.

>confirmed: tested with KK 11.0.1 on h3ulcb and h3ulcb+kf : default sound level is ok.
>As we don't have refhw board, we can't reproduce but I suspect that asound.state is missing or doesn't describe the appropriate soundcard.

Thank you for confirming of h3ulcb(+KF) case.

I don't hear clipping in my testing here, just somewhat higher volume.  It is that the alsa.states isn't matching now, as I'd not thought to change the reference hardware devicetree to use "ak4613" for the audio device to match the switch back to that from "rcar-sound" in the latest BSP update.  I'll upload the 1-liner to the devicetree for the reference hardware tomorrow.
