docs: rapidio: add it to the driver API

This is actually a subsystem description, with contains both
kAPI and uAPI.

While it should ideally be slplit, let's place it at driver-api,
as most things are related to kAPI and driver-specific info.

-RapidIO Subsystem Guide
-=======================
-
-:Author: Matt Porter
-
-Introduction
-============
-
-RapidIO is a high speed switched fabric interconnect with features aimed
-at the embedded market. RapidIO provides support for memory-mapped I/O
-as well as message-based transactions over the switched fabric network.
-RapidIO has a standardized discovery mechanism not unlike the PCI bus
-standard that allows simple detection of devices in a network.
-
-This documentation is provided for developers intending to support
-RapidIO on new architectures, write new drivers, or to understand the
-subsystem internals.
-
-Known Bugs and Limitations
-==========================
-
-Bugs
-----
-
-None. ;)
-
-Limitations
------------
-
-1. Access/management of RapidIO memory regions is not supported
-
-2. Multiple host enumeration is not supported
-
-RapidIO driver interface
-========================
-
-Drivers are provided a set of calls in order to interface with the
-subsystem to gather info on devices, request/map memory region
-resources, and manage mailboxes/doorbells.
