ASoC: spacemit: adjust FIFO trigger threshold to half FIFO size

Browse source

Set both TX and RX FIFO trigger thresholds (TFT/RFT) to 0xF (half of
the 32-entry FIFO) instead of 5. This provides better DMA efficiency
by allowing more data to accumulate before triggering a DMA request,
reducing the number of DMA transactions needed.
