arm64: dts: qcom: sm6125: Sort spmi_bus node numerically by reg

This node has always resided in the wrong spot, making it somewhat
harder to contribute new node entries while maintaining proper sorting
around it.  Move the node up to sit after hsusb_phy1 where it maintains
proper numerical sorting on the (first of its many) reg address
property.
