Subject: [PATCH] phy: qcom-qmp: Fix dts bindings to reflect reality

A few patches have landed for the qcom-qmp PHY that affect how you
would write a device tree node.  ...yet the bindings weren't updated.
Let's remedy the situation and make the bindings refelect reality.

Fixes: efb05a50c956 ("phy: qcom-qmp: Add support for QMP V3 USB3 PHY")
Fixes: ac0d239936bd ("phy: qcom-qmp: Add support for runtime PM")
Signed-off-by: Douglas Anderson <dianders@...omium.org>
