ehci: Check individual port status registers on resume

commit 294d95f2cbc2aef5346258f216cd9df570e271a5 upstream.

If a device plug/unplug is detected on an ATI SB700 USB controller in D3,
it appears to set the port status register but not the controller status
register. As a result we'll fail to detect the plug event. Check the port
status register on resume as well in order to catch this case.
