====================
net: stmmac: fix serdes power methods

The stmmac serdes powerup/powerdown methods are not guaranteed to be
called in a balancing fashion, but these are used to call the generic
PHY subsystem's phy_power_up() and phy_power_down() methods which do
require balanced calls.

This series addresses this by making the stmmac serdes methods balanced.
