ata: clean up how architectures enable PATA_PLATFORM and PATA_OF_PLATFORM
There are two options for platform device PATA support:
PATA_PLATFORM: Generic platform device PATA support
PATA_OF_PLATFORM: OpenFirmware platform device PATA support
If an architecture allows the generic platform device PATA support, it
shall select HAVE_PATA_PLATFORM. Then, Generic platform device PATA support
is available and can be selected.
If an architecture has OpenFirmware support, which it indicates by
selecting OF, OpenFirmware platform device PATA support is available
and can be selected.
If OpenFirmware platform device PATA support is selected, then the
functionality (code files) from Generic platform device PATA support needs
to be integrated in the kernel build for the OpenFirmware platform device
PATA support to work. Select PATA_PLATFORM in PATA_OF_PLATFORM to make sure
the needed files are added in the build.
So, architectures with OpenFirmware support, do not need to additionally
select HAVE_PATA_PLATFORM. It is only needed by architecture that want the
non-OF pata-platform module.
Reflect this way of intended use of config symbols in the ata Kconfig and
adjust all architecture definitions.
This follows the suggestion from Arnd Bergmann (see Link).
