From: Arnd Bergmann <arnd@arndb.de>

Portable drivers cannot use mach/platform.h, so move the
structure into its own header. With this, compile testing
can be enabled.

Hi PATA maintainers: we intend to merge this through
ARM SoC along with other IXP4xx refactorings unless you
have a specific problem with the patch.
