Subject: [PATCH v4 0/4] Enable IPQ9574 RDP433 eMMC variant

RDP433 can have NAND or eMMC based on a board level rework. Since the
same GPIOS are used for both the interfaces, only one of them can be
used. Add a new DTS file to disable NAND and enable eMMC.

v5: Cleanup the enable/disable of NAND/eMMC between the common and
    board specific DT files.
    Add regulator info

v4: Move sdhc properties to SoC dtsi.
    Disable nand in ipq9574-rdp433-emmc.dts
    https://lore.kernel.org/linux-arm-msm/20260202073322.259534-1-varadarajan.narayanan@oss.qualcomm.com/

v3: Disable nand in ipq9574-rdp-common.dtsi and enable it where
    required.
    Add r-b tags
    https://lore.kernel.org/r/20260129062825.666457-1-varadarajan.narayanan@oss.qualcomm.com

v2: Create two separate DTS files for the NAND and eMMC variants as
    suggested in the review.
