====================
net: stmmac: dwmac-oxnas: fix leaks and simplify pm

These patches fixes of-node and fixed-phydev leaks in the recently added
dwmac-oxnas driver, and ultimately switches over to using the generic pm
implementation as the required callbacks are now in place.

Note that this series has only been compile tested.
