If we write registers very fast we can endup in a situation where some

So wait for the fifo space to be available before reading/writing the
soundwire registers.
Out of curiosity, do you actually need to do a check in the read case as
well?
Yes, This is just to make sure the read command is finished and fifo is
ready with data.
If not we will be reading quickly an empty fifo!
The commit message talks about writes getting dropped, is the opposite
also a problem?
Its highly likely, for safety I have added support for both write and
read waits in this patch.
