Subject: [PATCH v5 4/4] arm64: dts: qcom: ipq9574: Enable eMMC variant

RDP433/RDP418 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 enable eMMC.

Signed-off-by: Varadarajan Narayanan <varadarajan.narayanan@....qualcomm.com>

v5: Add RDP418 eMMC variant

v4: Move sdhc properties to SoC dtsi.
    Disable nand (that is enabled in ipq9574-rdp-common.dtsi) here as
    the eMMC variant doesn't have NAND.

v3: As qpic_nand is disabled in ipq9574-rdp-common.dtsi, no need to disable
    it here. Just enable eMMC.
