ARM: dts: msm: move qcom,boot-option to HSP dedicated DTSI for sdxlemur

Having qcom,boot-option set to 0x1 on main sdxlemur devicetree
prevents other connects from being automatically enumerated.
Most connects do not require manual enumeration like Hastings
Prime (HSP) does. Therefore, move qcom,boot-option with 0x1 for
PCIe to HSP dedicated devicetree.
