Subject: [PATCH v3 2/4] arm64: dts: qcom: ipq9574-rdp433: Reorganize DTS to introduce eMMC support
The RDP433 has NAND and eMMC variants. Presently, only NAND variant is
supported. To enable support for eMMC variant, move the common nodes from
ipq9574-rdp433.dts to ipq9574-rdp433-common.dtsi. ipq9574-rdp433-common.dtsi
will be included in rdp433 NAND and eMMC DT files.
Reviewed-by: Konrad Dybcio <konrad.dybcio@....qualcomm.com>
Signed-off-by: Varadarajan Narayanan <varadarajan.narayanan@....qualcomm.com>

v3: Since qpic_nand is disabled in ipq9574-rdp-common.dtsi, enable it here.
Add 'Reviewed-by: Konrad Dybcio'
v2: Move common nodes into ipq9574-rdp433-common.dtsi
Trim down ipq9574-rdp433.dts and #include rdp433-common.dtsi
