usb: fix defined but not used warnings in hcd-pci.c
Shows up on ia64 builds (and possibly elsewhere) for configs that don't set PM_RUNTIME or PM_SLEEP as follows: drivers/usb/core/hcd-pci.c:383:12: warning: 'suspend_common' defined but not used drivers/usb/core/hcd-pci.c:438:12: warning: 'resume_common' defined but not used As per above, the functions are only used if RUNTIME/SLEEP are set, so make the two functions conditional on these Kconfig values.
