usb: dwc3: pci: add CONFIG_PM_SLEEP to suspend/resume functions

Browse source 
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SET_SYSTEM_SLEEP_PM_OPS are only used
when the CONFIG_PM_SLEEP is enabled. Unnecessary CONFIG_PM ifdefs
are removed.

drivers/usb/dwc3/dwc3-pci.c:215:12: warning: 'dwc3_pci_suspend' defined but not used [-Wunused-function]
drivers/usb/dwc3/dwc3-pci.c:224:12: warning: 'dwc3_pci_resume' defined but not used [-Wunused-function]
