Subject: [PATCH 9/9] arm64: dts: qcom: ipq5332: Remove eMMC support

Remove eMMC support from the IPQ5332 RDP442 board configuration to
align with the board's default NOR+NAND boot mode design.

The IPQ5332 RDP442 board is designed with NOR+NAND as the default boot
mode configuration. The eMMC and SPI NAND interface share
same GPIO
