1. Qualcom IPQ4019 SoC uses QPIC NAND controller version 1.4.0
   which uses BAM DMA Engine while IPQ806x uses EBI2 NAND
   which uses ADM DMA Engine.
2. QPIC NAND will 3 BAM channels: command, data tx and data rx
   while EBI2 NAND uses only single ADM channel.
3. CRCI is only required for ADM DMA and its not required for
   BAM DMA.
