Subject: [PATCH AUTOSEL 6.8 11/98] arm64: dts: qcom: sdm630: add USB QMP PHY support

From: Dmitry Baryshkov <dmitry.baryshkov@...aro.org>

[ Upstream commit bb5009a24ec3f2f2ec1e2ed7b8a5dcde9a9e28d9 ]

Define USB3 QMP PHY presend on the SDM630 / SDM660 platforms. Enable it by
default in the USB3 host, but (for compatibility), force USB 2.0 mode
for all defined boards. The boards should opt-in to enable USB 3.0
support.
