[PATCH] UHCI: various updates

This patch (as705) contains a small set of updates for uhci-hcd written
mostly by Dave Brownell:

  * Root hub suspend messages come out labeled as root hub messages;
    PCI messages should only come out when the pci device suspends.

  * Rename the reset() method to better match its init() role

  * Behave more like the other HCDs by returning -ESHUTDOWN for root-hub
    suspend/resume errors.

  * When an URB fails, associate the message with the usb device not
    the host controller (it still hides endpoint and direction)
