net: stmmac: platform: fix build warning when with !CONFIG_PM_SLEEP 

commit 2a48d96fd58a666ae231c3dd6fe4a458798ac645 upstream.

Use __maybe_unused for noirq_suspend()/noirq_resume() hooks to avoid
build warning with !CONFIG_PM_SLEEP:

>> drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c:796:12: error: 'stmmac_pltfr_noirq_resume' defined but not used [-Werror=unused-function]
     796 | static int stmmac_pltfr_noirq_resume(struct device *dev)
         |            ^~~~~~~~~~~~~~~~~~~~~~~~~
>> drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c:775:12: error: 'stmmac_pltfr_noirq_suspend' defined but not used [-Werror=unused-function]
     775 | static int stmmac_pltfr_noirq_suspend(struct device *dev)
         |            ^~~~~~~~~~~~~~~~~~~~~~~~~~
   cc1: all warnings being treated as errors
