USB: OHCI: fix build error related to ohci_suspend/resume

Commit 9a11899c5e69 (USB: OHCI: add missing PCI PM callbacks to
ohci-pci.c) added missing ohci_suspend and ohci_resume callback
pointers, but forgot that these callbacks are declared and defined
only when CONFIG_PM is enabled.

This patch adds a preprocessor conditional to avoid build errors when
PM is disabled.
