On Odroid C1+ and Odroid C2 USB feature is broken

It's being observed the after initiation of USB phy
the USB port goes in to suspend state, If we pass usbcore.autosuspend=-1
via command line USB hot plug seen to be working.

Another issue I observed is increase of USB interrupts event
even if there is not much activity on USB ports.

$ cat /proc/interrupts | grep usb
 35:   26462800          0          0          0     GIC-0  63 Level     c90c0000.usb, dwc2_hsotg:usb1

Changes added power node to usb phy and small code cleanup
in usb phy.

Previous version RFC.

Dopped the reoder of code changes as of now.

Thanks
