UHCI: make test for ASUS motherboard more specific

Browse Source 
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.)
