The Agilex devkit supports a separate NAND/eMMC daughter card.
The NAND/eMMC daughter card replaces the SDMMC slot that is on the default
daughter card and thus requires a separate board dts file.
New eMMC dts which is based on the existing NAND dts is needed to comply
with spec in which eMMC board ID is designated as 2.
