ARM: dts: imx6q: Use correct SDMA script for SPI5 core
commit df07101e1c4a29e820df02f9989a066988b160e6 upstream. According to the reference manual the shp_2_mcu / mcu_2_shp scripts must be used for devices connected through the SPBA. This fixes an issue we saw with DMA transfers. Sometimes the SPI controller RX FIFO was not empty after a DMA transfer and the driver got stuck in the next PIO transfer when it read one word more than expected. commit dd4b487b32a35 ("ARM: dts: imx6: Use correct SDMA script for SPI cores") is fixing the same issue but only for SPI1 - 4.
