USB: don't enable wakeup by default for PCI host controllers
This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers. The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.
It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences. As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again! We are better
off marking them as wakeup-capable and leaving wakeup disabled.
