ASoC: fsl-ssi: Fix baudclock handling
The baudclock may be used and set by different streams. Allow only the first stream to set the bitclock rate. Other streams have to try to get to the correct rate without modifying the bitclock rate using the SSI internal clock modifiers. The variable baudclk_streams is introduced to keep track of the active streams that are using the baudclock. This way we know if the baudclock may be set and whether we may enable/disable the clock. baudclock enable/disable is moved to hw_params()/hw_free(). This way we can keep track of the baudclock in those two functions and avoid a running clock while it is not used. As hw_params()/hw_free() may be called multiple times for the same stream, we have to use baudclk_streams variable to know whether we may enable/disable the clock.
