USB: xhci: Fix compile error when CONFIG_PM=n
Fix this error when CONFIG_PM is not enabled:
drivers/usb/host/xhci.c:675: error: implicit declaration of function 'usb_root_hub_lost_power'
Wrap xhci_suspend() and xhci_resume() into an ifdef CONFIG_PM, along with
the functions that only they call -- xhci_save_registers() and
xhci_restore_registers().
