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.
