There's no ASoC reason for doing this.  Anything that needs to be shared
between different DAIs can always be shared via the DMA driver.

Looking at the driver I rather suspect it only supports one FSI at once
and the capture support is also incomplete.  I don't see much problem
merging the driver with these limitations, it's generally been much
easier to get people to fix problems with merged drivers than to get
people to contribute entirely new drivers.
