This is not how any of this is supposed to work, it's unlikely to work
well with other devices.  If the device supports both master and slave
operation then you should let the machine driver pick if the SoC or the
CODEC is master via set_fmt(), randomly varying this at runtime is not
going to be helpful.

Maybe the name "master/slave" is confusing, these names come from internal
chip signals and do not represent the state of the i2s bus master. Our SoC
supports only master mode in the i2s bus. The Rx and Tx block each have an
independent bit to indicate if it is generating the clock for the i2s bus.
The i2s bus clocks need to be generated from either the Rx block or the Tx
block, but not both.
