Save/Restore context works only for dedicated host. Earlier it was
enabled even for OTG. This is corrected by modifying the check in
nvddk_usbphy.c. Checking for host mode instead of "IsHostMode" flag.
Bug 658225: USB host is not working on android/whistler USB port1 in OTG mode.
Tested on : Whistler USB1 OTG + USB3 host
Now OTG host is getting detected

To avoid the re-enumuration on wakeup from low power state, USB controller
context is saved before entering into suspend state and on resume the
stored context is restored. To restore the context properly, USB controller
needed to be programmed in the steps provided by the hardware team. With
this on wakeup, no re-enumurtion is happening.
