Add new optional DT property "cpu-system-clock-direction-out" to set
sysclk direction as "out" for the CPU DAI when using the generic codec.
It is set for both Tx and Rx.
If not set, the direction is "in".
The way the direction value is used is up to the CPU DAI driver
implementation.

This feels like we should be using the clock bindings to specify the
clock input of whatever is using the output from the SoC, though that's
a lot more work.
