stmmac: dwmac-socfpga: add PM ops and resume function
Implement the needed PM callbacks in the driver instead of relying on the init/exit hooks in stmmac_platform. This gives the driver more flexibility in how the code is organized. Eventually the init/exit callbacks will be deprecated in favor of the standard PM callbacks and driver remove function.
