Add support to call into snd_soc_dai_set_clkdiv() for both CPU and codec

This allows platforms to set hardware-specific values without providing an
own machine driver.
Why do we have anything that actually needs this? The devices with a
set_clkdiv() operation are pretty legacy at this point and most of them
should just be figuring out the dividers for themselves anyway.
The PXA platform CPU DAI still has it, and grepping also reveals some
Freescale and Samsung platforms.
If that's considered legacy, we shouldn't add bindings for it of course.
I can look into the PXA driver and see if it can auto-detect the
dividers itself. It won't be straight forward though as the clocking
setup also depends on configurations such as TDM slots, external vs.
internal clocks etc. Meh.
Thanks,
