If this is a CODEC requirement we should really be working this out from
the CODEC rather than adding a DT property on the I2S controller, or at
the very least putting this in the machine drivers.  The generic drivers
already have support for mclk-fs and there's an operation set_bclk_ratio() 
for them to use though we don't have a DT binding for that yet.
