    i3c: master: dw-i3c: Fix missing of_node for virtual I2C adapter

    The DesignWare I3C master driver creates a virtual I2C adapter to
    provide backward compatibility with I2C devices. However, the current
    implementation does not associate this virtual adapter with any
    Device Tree node.

    Propagate the of_node from the I3C master platform device to the
    virtual I2C adapter's device structure. This ensures that standard
    I2C aliases are correctly resolved and bus numbering remains consistent.
