arm64: dts: qcom: sm6115: Move USB node's 'maximum-speed' and 'dr_mode' properties to dts

Normally the 'maximum-speed' and 'dr_mode' properties
of a USB controller + port is dependent on the type of
the ports, regulators and mode change interrupt routing
available on the board(s).

So, move the same from the sm6115 dtsi file to respective
board file(s).
