ARM: dts: rockchip: setup DMA-channels for mmc0 and emmc for rk3188
This commit enable DMA-based transfers for SD/eMMC card adapters
and reduce number of interrupts produced by SD-card/eMMC-card
adapters.
Sometimes interrupts from SD-card/eMMC-card adapters running in
PIO mode blocks execution of hrtimers and I2S DMA callbacks for
a long periods (100 ms or more).
