rtw88: avoid unused function warnings
The rtw88 driver defines emtpy functions with multiple indirections
but gets one of these wrong:
drivers/net/wireless/realtek/rtw88/pci.c:1347:12: error: 'rtw_pci_resume' defined but not used [-Werror=unused-function]
1347 | static int rtw_pci_resume(struct device *dev)
| ^~~~~~~~~~~~~~
drivers/net/wireless/realtek/rtw88/pci.c:1342:12: error: 'rtw_pci_suspend' defined but not used [-Werror=unused-function]
1342 | static int rtw_pci_suspend(struct device *dev)
Better simplify it to rely on the conditional reference in
SIMPLE_DEV_PM_OPS(), and mark the functions as __maybe_unused to avoid
warning about it.
I'm not sure if these are needed at all given that the functions
don't do anything, but they were only recently added.
