[PATCH] USB: hcd suspend uses pm_message_t

This patch includes minor "sparse -Wbitwise" updates for the PCI based
HCDs.  Almost all of them involve just changing the second parameter of the
suspend() method to a pm_message_t ...  the others relate to how the EHCI
code walks in-memory data structures.  (There's a minor bug fixed there too
...  affecting the big-endian sysfs async schedule dump.)
