arm64: dts: qcom: msm8996-tone: Fix USB taking 6 minutes to wake up
The hardware turns out to be pretty sluggish at assuming it can only
do USB2 with just a USB2 phy assigned to it - before it needed about
6 minutes to acknowledge that.
Limit it to USB-HS explicitly to make USB come up about 720x faster.
Fixes: 9da65e441d ("arm64: dts: qcom: Add support for SONY Xperia X Performance / XZ / XZs (msm8996, Tone platform)")
