tegra usb: Enabling autosupend/selective suspend for USB host.
Enabling USB port suspend, when they is no activity happening on the on
port. Example: For an usb port, when a USB hub is conneted without any
devices on down stream, then hub upstream port can be suspended until
device(s) connected on down stream to hub. We enabled this feature for
whistler and harmony by enabling config paramater CONFIG_USB_SUSPEND.
Bug XXXXXX : Enabling auto suspend for USB host
Tested on : Harmony and Whistler E1108
Tested on Harmony by conneting 7 port hub to port2 of SMSC LAN hub
Tested on Whistler by connecting 7 port hub on USB3.
