Since ohci-hcd supports runtime PM, the .pm field in its pci_driver
structure should be protected by CONFIG_PM rather than
CONFIG_PM_SLEEP.
Without this change, OHCI controllers won't do runtime suspend if
system suspend or hibernation isn't enabled.

Greg:
I marked this for -stable because it fixes a bug. But the bug is a
benign one (under some configs, OHCI controllers won't go to low power
at times when they could) and nobody has complained about it. You can
decide whether or not this is really suitable for the stable kernels.
