usb: phy: qusb: Don't held QUSB PHY into reset state 



Currently QUSB PHY driver is keeping PHY into reset state and wait
for controller to bring it out of reset. Due to keeping PHY in reset
state (power down state) we are seeing no DP pulsing. Fix DP pulsing
issue by keeping QUSB PHY out of reset.
