From my side this changes fix the usb power issue on usb1 ports
This is follow up on my previous patches.
Changes from prevoius patch drop the initialization of usb0 otg port.

As per Martin's suggestion and input I have tried to fix below issue.
Fixed the phy power issue on the usb port.

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

From the shematics GPIOAO.BIT5 gpio input for the PWREN signal of the
USB_HOST controller (usb1), add missing phy-supply link for USB1 phy
controller this changes fixed the power issue on usb ports.
Changes help fix usb reset warning.
