This patch (as1482) adds a macro for testing whether or not a
pm_message value represents an autosuspend or autoresume (i.e., a
runtime PM) event. Encapsulating this notion seems preferable to
open-coding the test all over the place.

This is a minor change in the PM API, but most of the affected files
are in the USB subsystem. Therefore either Rafael or Greg might prefer
to accept this patch.
