spi: imx: adjust watermark level according to transfer length Previously DMA watermark level is configured to fifosize/2, DMA mode can be used only when transfer length can be divided by 'watermark level * bpw', which makes DMA mode not pratical. This patch adjusts watermark level to largest number (no bigger than fifosize/2) which can divide 'tranfer length / bpw' for each transfer.
