usb: phy-msm-qusb-v2: Move qusb_phy_host_init to qusb_phy_init 



Since notify_connect can be called from dwc3-msm driver and
hub driver, multiple phy initilizations is happening when HUB
is connected to the device.

Initialize qusb-phy for host mode in qusb_phy_init so that it
gets called only on core reset with HOST MODE FLAG set to
avoid multiple phy initialzations.
