[PATCHv4 net-next 2/8] net: ibm: emac: remove custom init/exit functions

[Rosen Penev]

c092d0be38f4f754cdbdc76dc6df628ca48ac0eb introduced EPROBE_DEFER
support. Because of that, we can defer initialization until all modules
are ready instead of handling it explicitly with custom init/exit
functions.
