ARM: dts: imx6q: Use correct SDMA script for SPI5 core
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.
Fixes: 677940258dd8e ("ARM: dts: imx6q: enable dma for ecspi5")
