usb: dwc3: pci: fix build warning on !PM_SLEEP



When building a kernel with CONFIG_PM_SLEEP=n, we
get the following warning:

drivers/usb/dwc3/dwc3-pci.c:253:12: warning: 'dwc3_pci_pm_dummy' defined but not used

In order to fix this, we should only define
dwc3_pci_pm_dummy() when CONFIG_PM_SLEEP is defined.

Fixes: f6c274e1 ("usb: dwc3: pci: runtime_resume child device")
