Hi Finn,

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.

This patch was tested successfully on a Powerbook 190 (MAC_IDE_BABOON)
using both pata_platform and ide_platform drivers.
The next step will be to try using these generic drivers with the other
IDE controller variants (MAC_IDE_QUADRA or MAC_IDE_PB) so that the macide
driver can be entirely replaced with libata drivers.

Changed since v3:
 - Updated Kconfig help text.

Changed since v2:
 - Enabled CONFIG_BLK_DEV_PLATFORM in multi_defconfig.
 - Replaced dev_get_drvdata() with platform_get_drvdata().

Thanks for the updates!

i.e. will queue in the m68k for-v5.10 branch, hopefully with an
Acked-by from the IDE maintainer.

when I'm talking to journalists I just say "programmer" or something like that.
