ARM64: dts: apalis-imx8qm-v1.1: spi: use gpio cs
It’s a limitation that one cannot use native SPI CS & DMA and have a continuous CS for the whole transfer. The CS is deasserted after each word sent. One can either use DMA and GPIO CS or one can use PIO mode. With this commit we change from using PIO mode to DMA mode and change the CS used from the IP provided one to GPIO CS on the same pin. This sync's the SPI configuration with the i.MX 8X based modules which already uses DMA with GPIO CS. Related-to: ELB-1278 Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>
