[PATCH 08/29] ARM: shmobile: r8a7778: Don't define SCIF platform data in an array

From: Laurent Pinchart <laurent.pinchart+renesas at ideasonboard.com>

The SCIF driver is transitioning to platform resources. Board code will
thus need to define an array of resources for each SCIF device. This is
incompatible with the macro-based SCIF platform data definition as an
array. Rework the macro to define platform data as individual
structures.
