commit 7ec05a6035480f3a5934b2b31222620b2e906163 upstream

Get rid of the CONFIG_PM_SLEEP ifdefery to fix the build error
and use __maybe_unused for the suspend()/resume() hooks to avoid
build warning:

drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c:769:21:
error: 'stmmac_runtime_suspend' undeclared here (not in a function); did you mean 'stmmac_suspend'?
769 | SET_RUNTIME_PM_OPS(stmmac_runtime_suspend, stmmac_runtime_resume, NULL)
| ^~~~~~~~~~~~~~~~~~~~~~
./include/linux/pm.h:342:21: note: in definition of macro 'SET_RUNTIME_PM_OPS'
342 | .runtime_suspend = suspend_fn, \
