memory: emif: Drop usage of platform_driver_probe()

There are considerations to drop platform_driver_probe() as a concept
that isn't relevant any more today. It comes with an added complexity
that makes many users hold it wrong. (E.g. this driver should have
better used __init instead of __init_or_module to mark functions only
relevant to .probe() and mark the driver struct with __refdata.)

This fixes a W=1 build warning:

	WARNING: modpost: drivers/memory/emif: section mismatch in reference: emif_driver+0x4 (section: .data) -> emif_remove (section: .exit.text)
