tegra usb:Enable host based on the odm usb property
USB host is getting enabled when the odm usb property is set to None.
During the system initialization host enable condition was not checked properly
when Odm USB mode property is set to "NvOdmUsbModeType_None". Due to the wrong
condition, host controller is turned on and consuming the power.
Bug 665409: [whistler/android/power] - USB power consumption has increased
Tested on AP20 whistler
