ARM: dts: imx6q: Use correct SDMA script for SPI5 core

Browse source

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 dd4b487b32 ("ARM: dts: imx6: Use correct SDMA script
for SPI cores") is fixing the same issue but only for SPI1 - 4.

Fixes: 677940258d ("ARM: dts: imx6q: enable dma for ecspi5")
