ASoC: S3C: Fix PCM RX FIFO settings

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.
