ARM: dts: msm: Enable QUSB phy related to USB secondary port on 8996



Leakage current is seen with QUSB PHY related power rail, although
QUSB PHY related secondary USB port is not enabled. QUSB PHY is
out of reset with POR. Hence enable QUSB PHY related secondary USB
port which allows QUSB PHY driver's probe to be called. As part of
QUSB PHY driver's probe, QUSB PHY is kept into reset state to reduce
leakage current.
