ARM: dts: Revert am335x mcasp ti-sysc changes
Without this McASP FIFO would constantly underflow. EDMA test via dmatest works though. Let's revert the change for now until we know the root cause. Reported-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Tested-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
