rapidio: add inbound memory mapping interface Add common inbound memory mapping/unmapping interface. This allows to make local memory space accessible from the RapidIO side using hardware mapping capabilities of RapidIO bridging devices. The new interface is intended to enable data transfers between RapidIO devices in combination with DMA engine support.
