serial: pmac_zilog: 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
marked the driver struct with __refdata to prevent the below mentioned
false positive section mismatch warning.)
This fixes a W=1 build warning:
WARNING: modpost: drivers/tty/serial/pmac_zilog: section mismatch in reference: pmz_driver+0x8 (section: .data) -> pmz_detach (section: .exit.text)
