pcm051: Enable DDR PHY dynamic power down bit
This is done already for am335x in 59dcf970d11ebff5d9f4bbbde79fda584e9e7ad4 and also applies for pcm051. It powers down the IO receiver when not performing read which helps reducing the overall power consuption in low power states (suspend/standby). Signed-off-by: Lars Poeschel <poeschel@lemonage.de>
