net: stmmac: mark PM functions as __maybe_unused

[ Upstream commit 81a8b079 ]

The newly added suspend/resume functions cause a build warning
when CONFIG_PM is disabled:

drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:324:12: error: 'stmmac_pci_resume' defined but not used [-Werror=unused-function]
drivers/net/ethernet/stmicro/stmmac/stmmac_pci.c:306:12: error: 'stmmac_pci_suspend' defined but not used [-Werror=unused-function]

Mark them as __maybe_unused so gcc can drop them silently.

Fixes: b7d0f08e ("net: stmmac: Fix WoL for PCI-based setups")
