In certain configurations without power management support, the
following warnings happen:
drivers/net/ethernet/mellanox/mlx4/main.c:4388:12:
warning: 'mlx4_resume' defined but not used [-Wunused-function]
4388 | static int mlx4_resume(struct device *dev_d)
| ^~~~~~~~~~~
drivers/net/ethernet/mellanox/mlx4/main.c:4373:12: warning:
'mlx4_suspend' defined but not used [-Wunused-function]
4373 | static int mlx4_suspend(struct device *dev_d)
| ^~~~~~~~~~~~
Mark these functions as __maybe_unused to make it clear to the
compiler that this is going to happen based on the configuration,
which is the standard for these types of functions.
Fixes: 0e3e206a3e12 ("mlx4: use generic power management")
