Move RTL8214FC power configuration to newly created suspend and resume
methods. A media change now only results in power configuration if the
PHY is not suspended, to avoid powering up a port when the interface is
currently not up.
While at it, remove the rtl8380 prefix from function names, as this is
actually not SoC-specific.
