mtd: nand: qcom: add bam property for QPIC NAND controller
The current driver only supports EBI2 NAND controller which uses ADM DMA. The latest QCOM SoC uses QPIC NAND controller with BAM DMA. NAND registers and programming sequence are same for EBI2 and QPIC NAND so the same driver can support QPIC NAND also by adding the BAM DMA support. This patch adds the is_bam in NAND property which will be checked for determining the DMA engine type.
