UHCI: make test for ASUS motherboard more specific
Instead of matching all motherboards whose name contains "A7V8X" for a remote-wakeup hardware bug, this patch (as829) matches only those boards whose name is exactly equal to "A7V8X". Later motherboards don't seem to have the bug. (In fact, it's possible that only one motherboard in the world has the bug. With only one user reporting problems, it's hard to tell.)
