I've applied this with a couple of additional fixups below. I've added
a dependency on BROKEN since the IISv4 support is not yet present so
there's no chance of it working yet.

This should be defined by the DAI driver, every user is going to need
it.

Doing this will break simultaneous playback and record - whichever of
them stops first will stop the PLL, removing the clock from the other.
I've removed the hw_free() function as a result.
I also note that you're not submitting and testing against the latest
ASoC code since the PLL API has been updated so that this won't build.
I've fixed it up this time but please do try to ensure you're working
with the latest code when submitting patches.
