Ugh, I just saw the dai_extclk stuff. That's probably also problematic
the other way - it'll break if someone decides to put a non-programmable
clock on there, or something that can't generate arbatrary frequencies
like a crystal plus divider. It's also not clear to me why the driver
ever uses the internal clocks if something external has been provided.
This does mean the change is safe, though - but it needs to be called
out in both the code and the changelog how this is happening.
