0cca901252
When PCM capture, sound recorded abnormally because of RX FIFO threshold settings are missing. So, This patch modify PCM RX FIFO setting codes same as TX. And for DMA, if PCM RXFIFO_DIPSTICK is not '0', it doesn't effect to DMA request, because DMA refer RX_FIFO_EMPTY flag as the DMA request.
