pmac_ide_init_hwif_ports duplicate

pmac_ide_init_hwif_ports exists in two forms in the latest benh kernel.  a generic coding in pmac_setup.c for pci chips (pcmcia iirc), and a coding in ide-pmac.c for pmac specific applications.  On boot, the ide-pmac.c coding is used, but since the pmac_setup.c coding is used in the ppc function structure setup, the pmac_setup.c code is used everywhere else.  One consequence is that mediabays are no longer hot swappable.

I wonder if the pmac_setup.c coding is needed.  If it is, where?  If the only places that need the ide-pmac.c coding are ide-pmac.c and mediabay.c, then the attached patch should be a good fix.  It works by explicitly calling the ide-pmac.c coding, then calling ide_register_hw instead of ide_register.  The more generic pmac_setup.c coding is left as default for any other hot swappable ata subsystem.

Is this code going in the correct direction?  (ide_register is kinda hinted as being legacy)

Thanks.
