USB: clarify usage of hcd->suspend/resume methods

The .suspend and .resume method pointers in struct usb_hcd have not
been fully understood by host-controller driver writers.  They are
meant for use with PCI controllers; other platform-specific drivers
generally should not refer to them.

To try and clarify matters, this patch (as1065) renames those methods
to .pci_suspend and .pci_resume.  It eliminates corresponding dead code
and bogus references in the ohci-ssb and u132-hcd drivers.
