pcnet32: Mark PM functions as __maybe_unused
In certain configurations without power management support, the
following warnings happen:
../drivers/net/ethernet/amd/pcnet32.c:2928:12: warning:
'pcnet32_pm_resume' defined but not used [-Wunused-function]
2928 | static int pcnet32_pm_resume(struct device *device_d)
| ^~~~~~~~~~~~~~~~~
../drivers/net/ethernet/amd/pcnet32.c:2916:12: warning:
'pcnet32_pm_suspend' defined but not used [-Wunused-function]
2916 | static int pcnet32_pm_suspend(struct device *device_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.
