[PATCH 1/6] rapidio: define top Kconfig menu in driver subtree

[Alexei Colin <acolin@isi.edu>]

The top-level Kconfig entry for RapidIO subsystem is currently
duplicated in several architecture-specific Kconfigs. This
commit re-defines it in the driver subtree, and subsequent
commits, one per architecture, will remove the duplicated
definitions from respective per-architecture Kconfigs.
