net/fec: clean suspend/resume

Commit 59d4289b converted fec to dev_pm_ops but
didn't update the suspend/resume functions thus leading to the following warning :
"initialization from incompatible pointer type" when CONFIG_PM is set.

This patch also fixe a few indentation and style around CONFIG_PM area.
