spi: imx: keep dma request disabled before dma transfer setup
Since sdma hardware configure postpone to transfer phase, have to disable
dma request before dma transfer setup because there is a hardware
limitation on sdma event enable(ENBLn) as below:
"It is thus essential for the Arm platform to program them before any DMA
request is triggered to the SDMA, otherwise an unpredictable combination
of channels may be started."
