arm64: dts: qcom: ipq5332: Add QPIC SPI NAND controller support
Add device tree nodes for QPIC SPI NAND flash controller support
on IPQ5332 SoC.
The IPQ5332 SoC includes a QPIC controller that supports SPI NAND flash
devices with hardware ECC capabilities and DMA support through BAM
(Bus Access Manager).
