usb: Add connected retry on resume for non SS devices
Currently usb_port_resume waits for up to 2 seconds for CONNECT status for SS devices only. This change will do the same thing for non-SS devices even though the reason is a little different. This will fix an issue where VBUS is turned off during system wide "suspend to ram" and some 2.0 devices take greater than the current max of 100ms to show connected after VBUS is enabled. This is most commonly seen on hard drive based devices and USB3.0 devices plugged into a 2.0 only port.
