Subject: ARM: shmobile: r8a73a4: Don't define SCIF platform data in an array

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.

(cherry picked from commit 4d32e834e19c34dcb510a7645ee8139c7e87bce4)
(Queued by Simon Horman for v3.14 but not yet in Linus's tree)
