As per Martin's suggestion and input I have tried to fix below issue.

Fixed the phy power issue on the usb port.

# cat /sys/kernel/debug/regulator/regulator_summary
    USB_VBUS                      4    2      0 unknown  5000mV     0mA  5000mV  5000mV
       phy-c1108820.phy.1         2                                 0mA     0mV     0mV
       phy-c1108800.phy.0         2                                 0mA     0mV     0mV

Fixed the OTG phy warning and initilizaion of usb0_phy

# lsusb -t

    |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/4p, 480M

/:  Bus 01.Port 1: Dev 1, Class=root_hub, Driver=dwc2/1p, 480M

Now hotpluing of usb device is working on odroid c1+ boards.
TODO: need to initialize the otg usb port to accept usb device.

Any input are welcome

Best Regards
