[PATCH v3 2/2] arm64: dts: socfpga: agilex5: add NAND daughter board

[niravkumar.l.rabara@intel.com]

From: Niravkumar L Rabara <niravkumar.l.rabara@intel.com>

The Agilex5 devkit supports a separate NAND daughter card.
The NAND daughter card replaces the SDMMC slot that is on the default
daughter card thus requires a separate board dts file.
