USB: unify reset_resume and normal resume

This patch (as919) unifies the code paths used for normal resume and
for reset-resume.  Earlier I had failed to note a section in the USB
spec which requires the host to resume a suspended port before
resetting it if the attached device is enabled for remote wakeup.
Since the port has to be resumed anyway, we might as well reuse the
existing code.

The main changes are:

	usb_reset_suspended_device() is eliminated.

	usb_root_hub_lost_power() is moved down next to the
	hub_reset_resume() routine, to which it is logically
	related.

	finish_port_resume() does a port reset() if the device's
	reset_resume flag is set.

	usb_port_resume() doesn't check whether the port is initially
	enabled if this is a USB-Persist sort of resume.

	Code to perform the port reset is added to the resume pathway
	for the non-CONFIG_USB_SUSPEND case.
