[PATCHv6 net-next 2/7] net: ibm: emac: remove custom init/exit functions

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.

As a consequence of removing explicit module initialization and
deferring probe until everything is ready, there's no need for custom
init and exit functions.

There are now module_init and module_exit calls but no real change in
functionality as these init and exit functions are no longer directly
called by core.
