Set Transmit Data Level(TDL) and Receive Data Level(RDL) to 16 samples.
Without this setting, the TDL is default to be 0x00 (means 0 sample),
and the RDL is default to be 0x1f (means 32 samples).

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

We can get into an infinite loop if the I2S_CLR register fails to
clear due to a missing break statement, so add that.
