Subject: [PATCH] USB: OHCI: Allow runtime PM without system sleep

commit 69820e01aa756b8d228143d997f71523c1e97984 upstream.

Since ohci-hcd supports runtime PM, the .pm field in its pci_driver
structure should be protected by CONFIG_PM rather than

Without this change, OHCI controllers won't do runtime suspend if
system suspend or hibernation isn't enabled.
