ide/macide: Convert Mac IDE driver to platform driver
Add platform devices for the Mac IDE controller variants. Convert the macide module into a platform driver to support two of those variants. For the third, use a generic "pata_platform" driver instead. This enables automatic loading of the appropriate module and begins the process of replacing the driver with libata alternatives.
