arm64: dts: qcom: qcs8300-ride: Enable second USB controller on QCS8300 Ride

Enable secondary USB controller on QCS8300 Ride platform. Since it is a
Type-A port, the dr_mode has been set to "host". The VBUS to connected
peripherals is provided by TPS2559QWDRCTQ1 regulator connected to the
port. The regulator has an enable pin controlled by PMM8650. Model it as
fixed regulator and keep it Always-On at boot, since the regulator is
GPIO controlled regulator.
