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:

error: 'stmmac_runtime_suspend' undeclared here (not in a function); did you mean 'stmmac_suspend'?
