This patch adds support for suspending, resuming, and remote wakeup
detection on root hub ports to the UHCI driver.  It doesn't add support
for suspending or resuming the root hub itself (beyond what's already
there) -- that will require considerably more work.  But at least devices
plugged directly into the computer will interact nicely with power
management.

Of lesser importance, the patch also simplifies some constant expressions.
