USB: Extend pci resume function to handle PM events
Currently, the pci_resume method has only a flag indicating whether the
system is resuming from hibernation. In order to handle all PM events like
AUTO_RESUME (runtime resume from device in D3), RESUME (system resume from
s2idle, S3 or S4 states) etc change the pci_resume method to handle all PM
events.
